    Proyecto DoQmail - Documentación y soporte a qmail en castellanoqmail francophonePlease note that this site is a reference for qmail users. It's
not designed to be easy to use -- it's designed to be comprehensive.
There are things in here which have sharp edges! If you're looking
for a tutorial site, visit Dave Sill's excellent Life With Qmail site.
qmail is a modern SMTP server which makes
sendmail obsolete, written
by Dan Bernstein, who also has
a web page for qmail. qmail
is a secure package. You can download
netqmail 1.06 (Redhat RPMs, and Debian .debs, HP-UX, Gentoo, and OpenBSD ports) and redistribute qmail for
free. You can get the "big
picture" of how qmail is organized. You should read Life with qmail.
There is a discussion
list and an announcements list
for qmail users, maintained by Dan Bernstein using qmail, of
course. There's also an archive.
You can search it.
It's also archived at The Aims Group, at Gossamer
Threads, and in Mailbox-format
archives. Charles Cazabon has written some guidelines for posting
to the list. There is also an FAQ, providing answers to frequently-asked
questions. qmail is now
open source.
Dan's updated FAQ is also available in other file
formats, and in Spanish. A number of large Internet sites are using qmail: USA.net's
outgoing email, Address.com, Rediffmail.com, Colonize.com, Yahoo!
mail, Network Solutions, Verio, MessageLabs (searching 100M
emails/week for malware), listserv.acsu.buffalo.edu (a big listserv
hub, using qmail since 1996), Ohio State (biggest US University),
Yahoo! Groups, Listbot, USWest.net (Western US ISP), Telenordia,
gmx.de (German ISP), NetZero (free ISP), Critical Path (email
outsourcing service w/ 15M mailboxes), PayPal/Confinity,
Hypermart.net, Casema, Pair Networks, Topica, MyNet.com.tr,
FSmail.net, Mycom.com, and vuurwerk.nl.  Charles Cazabon, Dave Sill,
Henning Brauer, Peter Samuel, and Russell Nelson have put together a netqmail-1.06 distribution of qmail. It is
comprised of qmail-1.03 plus the recommended
patches and some documentation.

[index] | | Author's Enhancement Software for qmail | | | | | | | | |
Enhancements and additions to qmail by its author, Dan Bernstein.
- ezmlm has its own section.
- The serialmail
package delivers mail from a Maildir to an SMTP server.
- The Unix Client-Server TCP
package makes ordinary Unix programs into TCP/IP servers and/or
clients. In particular its tcpserver program should be used with
qmail instead of inetd. This package now includes Dan's rblsmtpd package for blocking spam using the RBL.
Gerrit Pape has written man pages for ucspi-tcp-0.88,
daemontools-0.70,
and daemontools-0.76
to complement Dan's online HTML documentation.
Interestingly, William Baxter announced ucspi-ipc
and Bruce Guenter announced ucspi-unix within two days
of each other. Same idea, different implementations.
Bruce Guenter also has written ucspi-proxy. It passes
data back and forth between two connections set up by a UCSPI server
and a UCSPI client.
- William Baxter wrote ucspi-ssl
which uses OpenSSL to encrypt connections.
- Scott Gifford
has written an implementation of
UCSPI-TLS for qmail, which adds STARTTLS (RFC 2487) support to
qmail-smtpd and STLS (RFC 2595) support to qmail-pop3d while isolating
the encryption in a low-privilege process for security. You can get
UCSPI-TLS
patches for qmail, sslserver, and mailfront, along with a detailed
UCSPI-TLS on qmail HOWTO.
- Levent Serinol wrote a simple
patch which adds mysql
support to tcpserver.
- The daemontools package
monitors, controls, and logs the execution and output of long-running
programs, often called daemons.
Tetsu Ushijima wrote qmail-conf,
which creates an appropriate set of files to use daemontools to start
up qmail services.
- The qmailanalog package
analyzes qmail log files in various ways. Russ Allbery has written
tai64nfrac,
which converts the tai64n that daemontools-0.63 produces into the
fractional seconds that qmailanalog expects. Peter Samuel has
implemented the same idea as a patch
to daemontools using Dan's coding style (Jay Soffian also wrote
one substantially similar to Peter's). Finally (hopefully) John Levine
went ahead and fixed qmailanalog to accept
tai64n dates.
- Georg Lehner has made qmailanalog
better integrated with multilog.
- The dot-forward package
emulates sendmail's .forward file processing.
- The fastforward package
supports forwarding tables under qmail.
Mirko Zeibig has an RPM with fastforward
with a .qmail-default and a "standard" /etc/aliases-file in it.
- The checkpassword
package authenticates users using a generic interface. It is required
by qmail's included POP3 server.
- Dan has a checklist for users converting from
sendmail to qmail.
- Dan has written a reference manual for SMTP.
- You can't find a more secure DNS server than djbdns. If you thought the DNS was hard
to understand, you're wrong. It's not the DNS that's difficult --
it's just BIND.
- If you just want to publish information via the web or ftp and you
don't want to worry about security holes, consider using publicfile.
- ezmlm-showctl prints out the ezmlm
configuration in a readable manner.

[index] | | User-Contributed Software for Qmail | | | | | | | | |
General software contributed by users and supporters of qmail.
- Harald Hanche-Olsen has written some code to do dot-locking. Dot-locking is slightly unreliable, so
Dan doesn't support it in qmail.
- Seth
Alves hacked on maildir.module-970707 until it worked (mostly) with
imap-4.1.BETA.
- Mattias Larsson wrote a preliminary patch to IMAP4rev1
which lets it work with Maildirs. David Harris has improved that patch
to make a production quality UW-imap server with Maildir support.
And in his turn, Herbie has updated the Maildir patch for the latest UW IMAP server.
- David Summers has a qmail-imap Linux RPM.
This is a version of the IMAP/POP server that works with QMAIL, using
Mattias's patches. The three differences are:
- Mail is delivered and picked up from ~user/Mailbox
- Mail can be delivered and picked up from ~user/Maildir/ (see README.maildir)
- CRAM-MD5 authentication has been added to the IMAP server.
-
Sam Varshavchik wrote a Maildir-only IMAP server
called Courier IMAP.
- Ali Lomonaco has a patch for finger so it knows to look in $HOME
for a Mailbox. It was written for the finger from FreeBSD 2.2.2,
which is probably the standard BSD finger.
- Giles Lean didn't like the idea of patching majordomo, so
following a suggestion from J.T. Conklin that he found in the list
archives he wrote a majordomo-inject
script and some documentation on how to use it. Needs Perl 5.004.
Nathan
J. Mehl has thrown together a bourne shell script to automagically
create all of the
necessary aliases for a majordomo list with digests in a Qmail
environment that uses Giles majordomo-inject.
- Julie Baumler is using
UIUC's ph to redirect mail on her mail hub. She wrote a note on how
to configure qmail to use ph.
- Russell Nelson's checkhomeownership script will report on
users who don't own their home directories or Maildirs. This is
important to run before starting up qmail, because sendmail doesn't
care a whit whether the user owns their home directory, but home
directory ownership is how qmail decides if the user exists or not.
If you have a mail hub, and you've botched the home directory
ownership, the users will never be logging into it, so they won't
notice. And you won't notice either, until they run screaming to you
that they haven't gotten the important mail they wanted, and their
correspondent noted that the mail bounced.
- David Summers has
some perl
scripts that work with maildir2smtp. Now uses APOP-style
authentication.
- Russell Nelson's newbox script to create new
maildrops for users who don't have login accounts on their mail server.
- Chris Garrigues wrote a program to pretty-print
Received: lines.
- Brian
T. Wightman has written a delayed-mail
notifier.
- Another delayed-mail
notifier is available from Matt Ranney.
- Mark Delany has a rmail
for people receiving ! addresses via UUCP. It parses ! addresses,
applies a number of simple pattern matching rules to convert them to
FQDN addresses and injects them into qmail.
- Russell Nelson has a program
to eliminate duplicate messages. It has
two modes of operation -- strict and loose. Strict only eliminates
perfect duplicates, whose only difference is in the Received: lines.
Loose eliminates duplicates that have identical From: Date:,
Message-Id: and body parts.
-
Peter Samuel has expanded on Russell's program and written a
duplicate eliminator that uses dbm hash file(s) instead of a text
file. It also has improved exception handling and provisions for sites
without the MD5 perl module.
- Russ
Allbery uses Majordomo with qmail. He has a FAQ on
the subject.
- David Harris has a system to only allow hosts who have authenticated via the
POP3 server to relay mail using qmail. This does not require
patching the POP or SMTP servers, but is implemented by two programs
which cleanly interface into the system, and can work with most any
POP or IMAP server.
- Petr
Novotny wrote an alternative to Russell Nelson's Open-SMTP patch
for checkpassword. His code is a PAM
module which calls external program to log $TCPREMOTEIP. It
requires a PAM-enabled checkpassword.
- Mark Willcox wrote postpop, which
is a simpler SMTP after POP solution.
- Michele
Beltrame has a tool to view the qmail
queue (with colored display), view messages in it and delete
messages. It's very simple and written in Perl.
- Jeremy Kister wrote a qmail-queue
manipulation tool.
- Keith
Burdis has written several qmail programs,
including dotqmail2alias, alias2dot, deliver, and compactor/exploder
- Eric Huss has released queue-fix
1.4. It repairs or generates a qmail queue structure. You can
use this to help move your queue location, or if you regenerate the
file system and the inode numbering changes. It will also fix
permissions and ownerships of the files. Eric reports that Matthew
Harrell wrote a patch to queue-fix
which makes it work with Russ Nelson's big-todo patch. Patches upon patches!
- Harald Hanche-Olsen has a shell/awk/gnu-find script which renames a queue so that it has the right
filenames (corresponding to inodes).
- Charles Cazabon wrote queue_repair.
queue-repair is a qmail queue diagnostic and repair tool, written in
Python, and licensed under the GPL.
- Peter Samuel has a
qmail-compatible
vacation program.
- Jason van Zyl has a patch to the cyrus imap server so that it authenticates out of a
cdb (the same hash format that users/assign uses) instead of
kerberos or /etc/passwd. And he has a perl script that allow you to
enter users into the system and it takes care of updating the
users/assign file, and the cdb file that cyrus is using to
authenticate from.
- Bruce Guenter wrote qlogtools, a set of tools
useful in analyzing or producing logs from qmail and other packages.
- Monte Mitzelfelt has a program which sorts a qmail
log file by message delivery.
- Ismail Yenigul has a qmail
log analyzer tool called IsoQlog.
-
Bruce Guenter wrote his own implementation of the mini-qmail idea,
only his (nullmailer)
has a queue for more reliablity. It supports SMTP and QMQP, so it's a
drop-in replacement for qmail-qmqpc.
- Eric Hess needed longer timeouts
for qmqpc. The timeouts are hard coded in qmail-qmqpc. They
tend to be on the low side (10 seconds to connect, 60 seconds to
read/write). He uses some automated systems with qmqp and sometimes
the servers are overloaded and can't respond in that timeframe.
- Jay Austad has his qmqpc rotating the server list by a random
amount. This distributes the load over multiple qmqp servers.
- There are a number of web interfaces for reading mailboxes:
- Sam Varshavchik's sqwebmail.
- horde.org's IMP. Requires PHP and an IMAP/POP3 server.
- @.
- Twig. No frames, no javascript.
- oMail-webmail
is a simple Webmail solution for mail servers based on qmail and
optionally vmailmgr. This a GPL project, maintained by Olivier Müller. The mails are read
directly from Maildirs on the harddisk, which is much quicker than
using protocols like POP3 or IMAP. Other features includes multiple
language support (currently English, French, German and Italian),
folders and addressbook support. oMail is programmed in
Perl. Developers and translators are welcome to subscribe to the devel mailing
list.
- iGENUS is a chinese webmail
system for perl + qmail + vpopmail + mysql.
- Atmail is a complete
Webmail client for qmail supporting POP3/IMAP accounts. Streamlined
interface supporting Ajax and multiple Webmail templates and themes.
- VisualOffice supports Maildir++.
- Several autoresponders are available:
- Vyacheslav Ignatyuk wrote an alpha version of a qmail
manager module for webmin. It's a first alpha version,
so may be unstable.
-
Peter Green has some code to Archive and process log files
generated by qmail-send and qmail-smtpd.
- William E. Baxter has released qtools, a
suite of utilities for use in .qmail files. The tools support
applying a filter to a message body, message head, or entire message;
conditional delivery of a message to a Maildir; and configuration of
simple autorepliers.
-
Sam Varshavchik has a local delivery agent called Maildrop that has
a custom filtering language more readable than procmail's.
- Russell Nelson has a program called no-alternative, which picks the text/plain
part out of a MIME multipart/alternative message, and forwards it to
$USER-alternative.
- Russell Nelson and Magnus
Bodin have conspired to write some scripts and documentation to throw
information about qmail into
mrtg.
- Inter7 has their own MRTG configuration
- Chris Dent wrote Qmail::Queue.pm.
- oMail-admin is a PHP4-based
Web-administration solution for mail servers based on Dan
Bernstein's qmail and Bruce Guenter's vmailmgr.
- Dru Nelson has an incoming message
filter
- Dru Nelson has an
administrator's program to remove
queued mail that has a certain string in it.
- LinuxMagic has written qmail-remove
to remove emails from the queue. If they match a string, they are
moved to a temporary directory.
- Mail2DB -- Store incoming mail
in a PostgreSQL database. Mail2DB is suitable
for putting in a .qmail/.forward file and will archive e-mail to a SQL
database. Currently, there is only the storage component. This was
written because somone on a LUG list expressed interest in such a
system, but he only knew PHP (which isn't an ideal language for
calling from a .qmail file ;-). Hopefully a user interface will be
forthcoming.
- Russ Nelson has a qmtpd tarball for people using
0.70 or later daemontools with qmail.
Just drop it into your /service directory, and five seconds later,
you're running qmtpd. Don't forget to set your lowest MX priority to
12801, or all your deliveries will occur using SMTP. This is a
companion to his qmail-remote patch.
- Vmailadmin is a web
application that allow your client to administer the pop accounts in
his domain, easily and with security, without the need to contact
ISP staff.
- Alex Kramarov has created qmail-print-queue to print
the qmail queue contents - it runs on all messages and displayes
the from:, to: and date: headers; can also dump the full header of the
message if ran with "-h" switch (if mess822 is properly installed). It
is useful in conjunction with monitoring tools like qmail-mrtg and
others.
- Andrew Richards has written a set of tools for
managing multiple virtual domains using hashing to distribute maildirs called
qmail-hashdir.
- Mahlon Smith has written a
general new mail
checker, useful if you use the mutt MUA and procmail to filter
incoming mail to Maildirs, since there isn't a built in mechanism for
doing this from within mutt.
- qmail-qsanity-0.52 checks your
queue data structures for internal consistency. If it finds any
problems, it prints a warning to stderr. Plans are to change it to
generate shell commands which will correct the problems.
- qmail-lint-0.55
checks your qmail configuration for common problems. Prints warning
or error messages to stdout.
- Davide Giunchi wrote qmail-masq[uerade].
It will masquerade the internal address with an external one when
sending email from local network users to the external internet users.
- Todd A. Jacobs has a program to
generate random
extension addresses.
- Wolfgang Pichler wanted graphs
from logs, so he wrote qmailalizer.
- Bruce Guenter wrote mailfront, a package
containing customizeable network front-ends for mail servers;
specifically SMTP and POP3. Supports SMTP auth and POP3 AUTH
PLAIN and LOGIN.
- Mark Delany wrote set_supplementary_groups, which
lets you gain group permissions for the groups you are in in
/etc/group. In particularly mailman requires this.
- LinuxMagic is porting their
Anti-Spam/Valid User checking program, magic-smtpd, a
drop-in replacement for qmail-smtpd over to opensource. Features
checking for Valid Users, Spam conditions, and smtpd RCPT-TO rate
limiting, all at the smtpd level to reduce server loads before it hits
the queue. Supports stock qmail, qmail/vpopmail, and LinuxMagic
Mailserver installs.
- Larry Engleman has a Qt GUI
installer
- Andreas Aardal Hanssen has
written Binc IMAP. It's
invoked just like qmail-pop3d so it fits in smoothely in a vanilla
qmail system. Works fine with vhkpwd or any checkpassword-compatible
authenticators.
- John Wiggins has a C/C++ CGI
program for the control of qmail.
- Erwin Hoffmann wrote Newanalyse, helping the
sysadmin in processing multilog logfiles.
- Erwin Hoffmann wrote QMVC - Qmail Mail and
Virus Control is an unidirectional Mail Filter and Virus Scanner
for Qmail. It runs from your .qmail file.
- Ian Stewart wrote qmail-logfilter,
which discards the DATA phase of an smtp session.
- N. Ersen Siseci wrote Zabit, a C-language qmail
content filter.
- EnderUNIX has
updated qsheff, a
qmail-queue replacement to filter mail traffic and more. It
supports body filtering, subject filtering, attachment filtering,
quarantine, white/black list, single line logging for qmail and many
features.
- Russ Nelson wrote qmail-dk, which is a qmail-queue
replacement that signs and verifies DomainKeys signatures. Building on Gentoo
- Sorrawut Korsuwansiri wrote qmail-track,
which he uses to locate all the logfile records associated with a
particular pair of email addresses.
- Inter7 has updated simscan, a qmail-queue
replacement to reject unwanted email. Simscan is a simple program
that enables qmail-smtpd to reject viruses, spam, and block
attachments during the SMTP conversation so the email never makes it
into your computers. It is completely open source and uses other open
source components. Very efficient and written in C.
- Dovecot is an open source IMAP and
POP3 server for Linux/UNIX-like systems, written with security
primarily in mind.
- Niki Denev wrote qstat-gid.
It prints info about the messages in the qmail queue sorted per GID.
He uses it to quickly see if any user sends excessive amounts of
mail/spam and fills the queue.
- Skaarup has written a package for
analyzing logfiles for a lot of
Dan's tools.
- Folkert van Heusden wrote multitail, which
monitors multiple logfiles. MultiTail lets you view one or
multiple files like the original tail program. The difference is that
it creates multiple windows on your console (with ncurses).
- Richard Lyons wants to sign
messages using domainkeys after verh has
modified the message, so he added code to qmail-remote to [re]sign the
message.
- EZIX has a NoRelaySMTP,
which writes email directly into a user's Maildir.
- Chris Hardie has written a
program to migrate
from IMail Server to qmail/vpopmail.

an EZMLM
list splitter. It forwards subscribe/unsubscribe requests from a
main list to one of a set of sublists based on the target address
(hash or domain name). This way, the list can be split into a number
of hosts for load splitting or geographic splitting without
inconveniencing the user (who always deals with the main list).
- Özgür Kesim has a ezmlm HOWTO for
advanced mailing lists.
- Steve Peterson
implemented a simple web
subscribe/unsubscribe interface to ezmlm.
- Michael Hirohama wrote Ezmlm-Thresh, which
allows EZMLM mailing list messages to be limited to a threshold per
subscriber.
- Guy Antony Halse has a web
interface to ezmlm called ezmlm-web, currently at
2.1. It has improvements over Glen Stewart's version.
- Glen Stewart has improved on Guy Antony Halse's EZmlm-Web 1.02.
He's calling his version EZmlm-Web
v1.0.2gs1.2. The gs1.2 version suffix modifications are fairly
extensive and done by Glen Stewart. Some of the most notable changes in this release include:
- list owner logon screen & password
- ListMaster access/control from filtered, configurable IP addresses
- Only the ListMaster can create and delete lists
- skeleton support for WebGlimpse indexing of selected list archives
- spam filter option for list owner addresses
- tooltip help for all list configuration settings
- case-insensitive list and subscriber address sorting
- list owner can change their owner address
- configuration tour (help) for list owners
- many other fixes and enhancements
- Sergiusz Pawlowicz wrote ezmlm-cgi-py, a
more approachable (i.e. Python, not djb-C) version of "the Freds"
ezmlm-cgi archive formatter.

[index] | | Living with Qmail - Tips & Advice | | | | | | | | |
Some good advice for new qmail users, contributed by qmail users.
- Did you restart qmail? I find that to be a help for a lot of
qmail problems. :-) [John Mitchell]
- You should also check the permissions very carefully on all of
the necessary directories and files. [John Mitchell]
- You must also put the virtual domain into
control/rcpthosts or the mailer will bounce the message
with a notice saying that the host wasn't in rcpthosts. [John Mitchell]
- Of course, you must also be the MX for the virtual hosts. I had
a problem in my setup that was driving me nuts until I realized that
my DNS provider had missed an MX update request. [John Mitchell]
- Check all lines in sendmail.cf beginning with M. Any that
contain P=[IPC] or P=[TCP] should also have
E=\r\n. [Tim
Goodwin]
- You might want to limit posting to mailing lists.
- The right-hand-side of entries in
control/virtualdomains should begin with a username. If
you don't use a username, the mail will be handled by ~alias. But if
you forget, and create a user by that name, then the mail will
suddenly be handled by the user, which is probably not what you
intended to happen. Best to use, in this case, alias as
the username and avoid trouble. [Russ Nelson]
- remember to add 'preline' before
procmail or other filters when moving .forward to .qmail. [Ira Abramov]
- If you use qmail's
preline
utility, remember that preline expects to pipe the entire
mail message through the specified program. If the specified
program closes standard input before preline has finished, preline
will exit with a transient failure and you'll see the following
error in your logs:
deferral: preline:_fatal:_unable_to_copy_input:_broken_pipe/
You'll see this problem if you try to use the sendmail version of
vacation. Use Peter's vacation program
instead. [Peter Samuel]
- Run qmail from an init.d script [Larry Doolittle]
- You can usually create control/rcpthosts from
sed 's/:.*//' <virtualdomains | cat - locals | sort
>rcpthosts
[Russ
Nelson]
- Sometimes you need to use a database to
forward mail. Create ~alias/.qmail-default like this:
|if T=`
X`; then forward $T; else
echo "Sorry, no mailbox here by that name (#5.1.1)";
exit 100; fi
That all goes on one line. Fill in the X part with a program
that looks up the user, and exits with zero and prints the destination
address, or else exits nonzero if no match is found. By the way, the
X program probably should ignore case. For NIS, you would replace the
X in the above command with: ypmatch $LOCAL aliases .
[Russ Nelson]
- Similarly, you could also use a simple linear search text file
named mapping containing lines in the form
incoming:outgoing like this:
|if MAP=`grep -i "$LOCAL:" mapping` && T=`echo $MAP | awk -F: '{print $2}'` ;
then forward $T;
else echo "Sorry, no mailbox here by that name (#5.1.1)";
exit 100; fi
[Russ Nelson]
- Anything you print from a program run by a .qmail file ends up in
the log file.
[Russ
Nelson]
- You can do a reasonable imitation of sendmail delivery, including
.forward and /var/spool/mail, with
#!/bin/sh
exec qmail-start '|dot-forward .forward
|preline -f /bin/mail -f "$SENDER" -d "$USER"' splogger qmail
depending on your system's binmail interface. Of course, I recommend
throwing binmail away, but people who need to preserve /var/spool/mail
should still be able to use qmail.
[Daniel
J. Bernstein]
- If you want to have private .qmail files which only work on local
mail (e.g. a fax gateway), you can put the following test at the
beginning of it (all on one line):
| if [ -n "`sed -n -e '/invoked from network/p' -e 2q`" ]; then exit 100; else exit 0; fi
That is, peek at the headers, if the message came from the network, bounce
it, otherwise forward it along.
[John R. Levine]
- [Daniel
J. Bernstein] has three suggestions for allowing your users to
relay when they're not at a known IP address (which is the FAQ 5.4 solution):
- Use a secret IP address and port number, and you'll have much
better security than user-chosen passwords.
- Put a secret string into the HELO string sent by the client. This
will be visible to the fixup script, so you can reject messages with bad
passwords without changing qmail-smtpd---and it's still more widely
supported than XTND XMIT.
- Oh, you want real security? Check that all messages are PGP-signed by local users. I wouldn't be
surprised if PGP plugins are available for more clients than XTND XMIT
patches are.
- [Anand
Buddhdev] wrote turnmail, modified by
Russell Nelson for publication here, which wraps around qmail-pop3d
and triggers a serialmail delivery to the connecting host whose user
just authenticated themselves. Or, a Unix system can use fetchmail,
getmail
or an NT system pullmail.
- Dan Bernstein suggested that one might give ordinary users access
to qmail-qread through ucspi. Steinar
Haug implemented that suggestion thusly with a client that looks
like this:
#!/bin/sh
exec /local/etc/tcpclient -RHl0 -- 127.0.0.1 20025 sh -c 'exec cat <&6'
and he starts the server like this:
tcpserver -u126 -g120 -R 127.0.0.1 20025 /var/qmail/bin/qmail-qread &
- The default delivery instructions, which are invoked when a .qmail
file is nonexistent or empty, are found in the first parameter of
qmail-start. That's why the install instructions tell you to touch
.qmail-root .qmail-mailer-daemon and .qmail-postmaster.
- [Anand
Buddhdev] recommends pullmail, which is a
Windows NT program that pulls mail from a POP3 server, and stuffs it
into NT's SMTP server.
- [Mark
Delany] modifies FAQ 2.3 so he can use the same .qmail file for multiple UUCP sites:
Here is our .qmail-uucpfqdn-default file (all on one line)
|preline -df /usr/bin/uux - -r -gC -a"$SENDER"
`echo $EXT | cut -f2 -d-`!rmail "(${EXT3}@$HOST)"
And here is a sample virtualdomains entry:
some.domain:uucpfqdn-uuhostname
- Dan Bernstein noted that qmail will skip dns queries for incoming
mail with tcpserver -Hl your.host.name; and you can skip
them for outgoing mail with control/smtproutes.
- Harald Hanche-Olsen has a solution to the problem of mail that has
wrongly been queued for a remote host (because, say, you didn't have a
host in your locals or virtualdomains):
echo tcn.net:[127.0.0.1] >> /var/qmail/control/smtproutes
Now send qmail-send an ALRM signal.
- Hitesh Patel has a patch
for UnixWare 2.1.x and 7.0.x, which is not currently supported by
qmail.
By the way..... the patch above opens up the option of sending mail
to root... if you want this then just copy the right files into your
qmail source directory... if you don't go into conf-unusual.h and
comment out line 25 that says "#define ALLOW_ROOT_MAIL 1".
Probably a good idea to comment it out -russ .
- Daniel J. Bernstein suggests that if you have buggy clients that
send bare LFs, and you want to treat their messages the same way
sendmail does, you can simply run his fixcrio program instead
of qmail-smtpd for your outgoing mail relay. fixcrio then takes
qmail-smtpd as argument. fixcrio is part of the ucspi-tcp package.
- Balazs
Nagy likes to watch logs in a virtual terminal (/dev/tty8). He uses
... | tee >(accustamp | tailocal > /dev/tty8) | accustamp | cyclog
The extra accustamp seems to be needed to make it work with bash.
- Frederik Vermeulen says: If you don't want a specific
undeliverable mail to sit in the queue any longer, you can make it
reach the queuelifetime by running touch -d '1 week ago'
on its queue/info file. It will then be bounced after one
more delivery attempt.
- Russ Nelson has used qmail-local to deliver to a dynamic Mailbox
or Maildir name. He does it like this:
|qmail-local "$USER" "$HOME" "$LOCAL" "" "nodeliver" "$HOST" "$SENDER" "/path/to/users/maildir/here/"
- Harald Hanche-Olsen warns people to beware when patching Solaris
machines, because at least one patch restores the
/etc/rc?.d/[SK]??sendmail symlink. You might want to remove files
matching that name in your startup scripts.
- Vern Hart doesn't like a pile of .qmail files in his home
directory. So he uses users/assign to put them into a subdirectory:
=vern:vern:2244:18:/home/vern:::
+vern-:vern:2244:18:/home/vern:s/::
This puts .qmail in his home directory but everything
else is in .qmails/. This changes ~/.qmail-foo to
~/.qmails/foo and really cleans up his home.
-
Jim Simmons points out that you can stop linuxconf from creating a
potential security hole by removing the /usr/sbin/sendmail line from
/usr/lib/linuxconf/redhat/perm. If you don't do this, linuxconf will
change /var/qmail/bin/sendmail to running suid.
-
Dag Wieers wants to see all messages that are delivered to his
domain but were bounced because the user or alias does not exist. Since
you cannot forward and pipe in the same dot-qmail he found the following
solution to be his most simple option, .qmail-default:
|forward dag@mind.be >/dev/null 2>&1
|echo "Sorry, no mailbox here by that name. (#5.1.1)"; exit 100
This way someone can simply check those mails regularly and forward them
to the right person manually (which sometimes saves time when people are
waiting for feedback)
- Peter van Dijk suggests that
you have two services running smtpd, one using recordio and the
other not. He says that it's a great diagnostic tool. Create
/service/qmail-smtpd as you would normally. Create
/service/qmail-smtpd-recordio as a copy with recordio inserted, and
logging to a separate space (be sure to chmod this logdir tight
because recordio records complete emails). Create
/service/qmail-smtpd-recordio/down. The switchover is then simply:
# svc -u /service/qmail-smtpd-recordio ; svc -d /var/service/qmail-smtpd
and viceversa.
- Han Boetes blocks sites with no
reverse dns. He uses the following tcp.smtp file. The only thing
I would do differently is to set RBLSMTPD instead of just denying the
connection.
127.0.0.1:allow,RELAYCLIENT=""
172.16.11.:allow,RELAYCLIENT=""
=:allow
:deny
- Japheth Cleaver has a simple solution for stunnel. using a
wrapper script.
- Richard Lyons points out that
multilog has filtering capabilities, see
http://cr.yp.to/daemontools/multilog.html. If you leave recordio in
place you can select what bits of the output to write. For example:
multilog t '-* * > *' '-* * < *' /var/log/qmail/smtpd \
'-*' '+* * > 5*' /var/log/qmail/smtpd-err
will do the normal logging to /var/log/qmail/smtpd, and will
record 5xx errors sent by your server to the client in
/var/log/qmail/smtpd-err.
- Qmail-popup redirects stderr to
stdout, thus making it impossible to write a wrapper around
qmail-pop3d which writes to the logfile by writing to stderr. Being a
little cleverer with the shell, you can also redirect FD 7 onto stdout
like this:
/var/qmail/bin/qmail-pop3d-wrapper.sh /var/qmail/bin/qmail-pop3d Maildir 2>&1 7>&1
Once you've done that, qmail-pop3d-wrapper.sh can log to FD 7, like this:
#!/bin/sh
echo "qmail-pop3d: user $USER logged in from $TCPREMOTEIP:$TCPREMOTEPORT" >&7
$@
- Alex Greg likes to see the output
of svstat expressed in dhms instead of seconds.
- Erwin Hoffmann suggests a
one-line fix to the errno compilation problem. It works for most DJB
software:
cat error.h | sed -es/^extern\ int\ errno\;/#include\ \/ >error.h
Or, djb suggests that you edit conf-cc to read:
cc -O2 -include /usr/include/errno.h
- Russ Nelson suggests a method for
stopping qmail reliably. When you need to stop qmail to do
something, do it like this:
svc -d /service/qmail-s*
# wait for qmail-send to exit.
setlock /service/qmail/supervise/lock sh -c (
# do stuff here
svc -u /service/qmail-s*
)

[index] | | Alternative Checkpassword Implementations | | | | | | | | |
qmail-popup and qmail-pop3d are glued together by a program called
checkpassword. It's run by qmail-popup, reads the username and
password handed to the POP3 daemon, looks them up in /etc/passwd,
verifies them, switches to the username/home directory, and runs
pop3d. At least that's what the standard one does.
Some alternatives are listed below.
Mark
Delany has a clever way to test your checkpassword with a bit of
command line re-direction. For example, with username
fred, password bloggs,
printf "%s\0%s\0%s\0" fred bloggs Y123456 | /bin/checkpassword id 3<&0
will execute /bin/id if the password is right.
If you haven't a printf then enter the data into a file with your
favourite binary editor, such as emacs, and then it's simply:
/bin/checkpassword id 3<test.file Or use perl:
perl -e 'printf "%s\0%s\0Y123456\0","fred","bloggs"' | ... Or use qmail-popup and use the 'user' and 'pass' commands:
/var/qmail/bin/qmail-popup /bin/checkpassword id - Jedi/Sector One has a checklocalpwd.c
that checks a configuration file in addition to the users mentioned in
/etc/passwd.
- Jos Backus has a mkpoppass/chkpoppass pair. It uses an
alternate username/password file and is written in perl.
- Bruce
Guenter has a virtual domain mail manager package called vmailmgr. It's designed to manage
multiple domains of mail addresses and mailboxes on a single host.
Co-operates with qmail for mail delivery and program control. Has
corresponding add/deluser and change-passwd commands, and CGI scripts.
Knows about shadow and MD5-encrypted passwords. Uses CDBs for the
virtual domain tables. Supports IMAP via an authentication module for
Courier-IMAP.
- Russell Nelson's pop-subaddr patch allows multiple maildirs per POP3
user, all of them authenticated with the same password.
- Alexey Mahotkin rewrote checkpassword-pam
from scratch.
- Petr
Novotny wrote an alternative to Russell Nelson's Open-SMTP patch
for checkpassword. His code is a PAM
module which calls external program to log $TCPREMOTEIP. It
requires a PAM-enabled checkpassword or any POP3/IMAP system that uses
PAM for authentication.
-
Bruce
Guenter has yet another SMTP relay control
package. It uses a setuid program called from checkpassword to avoid
patching checkpassword. Strictly speaking, it's not a patch, but it's
here so people can find it along with the others.
- Christopher
Johnson (EI39-1) wrote a virtual domains package with the
following features. Inter7 is now maintaining the current version,
called vpopmail.
- Dynamic delivery - no need to have dozens of .qmail files all over the place. Just a single .qmail-default handles all the deliveries
- Shadow password support - something that seemed to be lacking in the other programs
- Only takes up 1 entry in /etc/passwd - everything runs under a single UID/GID
- Decent documentation - actually, some docs I've come across for this are pretty good, but I had a bugger of a
time getting the things working (probably 'cos I'm using shadow'd passwords on my own Linux box).
- Delivers direct to a Maildir for use with qmail-pop3d
- Ken Jones has a program for administration of virtual domains
called QmailAdmin,
using the vchkpw program. It handles pop acccounts, aliases, forwards,
autorepsonder and ezmlm mailing list.
- Justin Hopper has a quota implementation for
QmailAdmin.
- Steve
Simitzis has XTND XMIT mods for
qmail-pop3d that also incorporate some patches found on this site.
- André Oppermann has patches to do user lookup (deliver and
retrieval via qmail-pop3) using LDAP. Cristiano Venturini has a site
in Italian for qmail-ldap.
- Pedro Melo has a patch to checkpassword-0.81 which uses a CDB file.
- Chris
Johnson wrote checkcdb, a
version of checkpassword that authenticates users from a cdb
database. It includes perl scripts to maintain the user database file.
- Shinya Ohira fixed a
security lapse in checkpw, which gets its password from a file in
the user's home directory, and allows both POP
and APOP authentication. Magnus Bodin has a copy if that site happens to
be unavailable.
-
Tong has a PostgreSQL
checkpassword.
- Matthias Andree has a patch to Dan's checkpassword
that allows checkpasswd to use an arbitrary base
directory for finding Maildirs
- Jesse
Sweetland has added Postgres support to his checkpassword and
qmail-getpw replacements. He calls the package sql-xpw. These differ from
Takeshi's code because his is a patch to qmail and this code is not.
- Ariel Kirsman has written a
checkpassword which authenticates using an NT domain. It is derived from
code taken from squid.
- Andrew Richards has a checkpassword
for Radius, written in C. It's based around Dan's
checkpassword, and uses the Radius client library from FreeBSD, as
well as MD5, since that's how Radius encodes its data.
- Larry M. Smith has a vanilla checkpassword.pl.
- Piotr Swebodzinski has a checkpassword for tru64 Unix.
- Scott Gifford has notes
for using checkpassword w/ Courier-IMAP.
- Andrew Richards has a checkpassword
that wraps around Courier-IMAP's authentication for use by
qmail-pop3d.
- Andreas Aardal Hanssen has a way
to run multiple
checkpasswords and authenticate against one, and if that
fails, then the other. If none succeed, it returns failure.
- David Phillips has a
checkpassword which authenticates via a pop3 connection.
While this may seem counter-productive, you can use it for smtp-auth
where the smtp server does not have direct access to the user database.
- Plácido Revilla wrote a
checkpassword that authentifies against a PHPNuke users database. This allows
administrators of these kind of portals to automatize the creation of
pop3 accounts in their system.
- Courierpasswd
allows users to to check and change their passwords using Courier
authentication modules. It can optionally read authentication tokens
from stdin and send logging information to syslog or stderr.
- Adam Aube's chkpass.pl
authenticates using a Squid auth helper program.
- Oliver Hitz authenticates
against a CDB file and works for SMTP-AUTH as well as for Courier
POP and IMAP.
- Tino Reichardt has a qpasswd
checkpassword.
- Ted Fines wrote a perl LDAP
checkpassword.
- Thomas Mangin's qmail-ldap-multi-auth
patch allows you to run a mix of qmail-ldap and vmailmgr domains on
the same machine.

[index] | | Yet More Qmail Addons | | | | | | | | |
Still need something more from qmail? The chances are good that you
can find it here, contributed by users and supporters of qmail.
- Paul Fox has created a getpwnam() patch for qmail
which causes it to use getpwname() to get the uids of its usernames.
- Evan Champion has a patch to
condredirect. It allows condredirect to handle the case where the
child has a permanent delivery error -- for example, when the program
condredirect is asked to run doesn't exist.
- John Saunders has a patch
to date822fmt.c which causes it to emit dates in the local
timezone.
- Chuck Foster implemented code (which Bill Nugent updated it to qmail
1.03) to bind the local address for smtp
client sessions to an address which is mapped using the remote address
as a key. This can be useful to bypass a firewall, or if you've got
split routing, or if you have a better non-publicized route to the
destination host.
- Russell
Nelson's qmail-popbull
program lets you create bulletins which get added to a user's
mailbox as they log in. Equivalent to an all-customers mailing list,
but takes up much less resources, and lets you withdraw bulletins.
-
Bruce
Guenter has a qmail
RPM which automatically applies a number of patches found here and
which comes with some scripts.
- Markus
Stumpf has a pair of qmail
patches, one to cause qmail-smtpd to log its disposition of mail,
and another to convince qmail-remote to use a fixed IP address other
than the one you get without binding to an address. Andy Repton has
ported the fixed IP address patch to
qmail 1.03. Damir Cifer has better instructions for his port.
- Chuck Foster originally wrote a patch for tcpcontrol. That
functionality got subsumed into tcpserver. John Levine has updated it
to the current version (0.84).
It allows you to:
- deny services based on domain names instead of IP addresses.
- distinguish between no PTR and wrong PTR DNS records.
- deny service to hosts whose forward and reverse DNS do not agree.
- Christopher K. Davis has a patch to accept oversize DNS
packets which works on both qmail's dns.c and tcpserver's dns.c.
If you don't want to patch qmail, you can ameliorate the problem
somewhat using djbdns, which
returns only the records you ask for, making for a smaller ANSWER
section.
- Bruce
Guenter has a patch which causes qmail programs to get
their userids, not compiled in via auto_uids.c, but instead by
looking at files in /var/qmail/owners.
- Bruce
Guenter has RPMs of daemontools.
- Bruce Guenter wrote supervise-scripts,
to help him start and stop supervise-managed programs in a more
controlled manner.
- Nick Leverton wrote a patch to qmail-send to cause it to suspend remote
delivery without needing to restart qmail.
- Ximenes Zalteca improved Dave's patch so that broken
versions of Eudora which emit a
CAPA command can still work with qmail's POP3 server.
- Fred Lindberg has a patch which causes qmail-send to preserving
the MIME-ness when bouncing MIME
messages. It requires and includes a patch to ezmlm, since it
breaks QSBMF.
- Jose Luis Painceira's patch deletes the body on big
bouncing messages. It's based on Fred Lindberg's patch (see
previous item). Note that if you use ezmlm, you may need Fred's patch
for ezmlm-return, which is not included here.
- Klaus-Uwe R. Ittner wrote a patch to make serialmail enclose the
bounced
message as a MIME part, in analogy with qmail-mime.tar.gz. Useful
for all those unfortunate people who use character sets other than
us-ascii and want to be able to decipher what bounced.
- There's also the qmail-verh
patch. This allows substitution of the recipient local/host parts
into the message. Useful for inserting a customized mailto: URL for
list-unsubscribe into the body of the message. Bernhard Graf has a fix for input
buffer boundary problems.
- Mrs. Brisby has written a
user/password based authentication
mechanism for qmail-smtpd. This lets your microsoft's outlook express
supports (outgoing mail server user name) and netscape 4.5 (and
above-betas) users securely roam. Users can use a slightly modified
version of their own checkpassword.c program as outlined in my own vchkpw.c that I use.
Also, two very simple perl scripts to perform pop3-based
authentication for qmail.
- Krzysztof Dabrowski has made some improvements to
Mrs. Brisby's SMTP-AUTH, to let it work with CRAM-MD5
and PLAIN.
- Traian Zvirid has additional
restrictions on top of Krzysztof's SMTP-AUTH patch.
- Eric M. Johnston's YAQSAP
(Yet Another qmail SMTP AUTH Patch).
- Frederik Vermeulen has written a
patch implementing RFC2487
(starttls) in qmail (qmail-smtpd as server, qmail-remote as
client). This means you can get SSL or TLS encrypted and
authenticated SMTP between the MTAs and between MTA and an MUA
like Netscape4.5.
- Oliver Hitz wrote a small tool to
manually test
SMTP-AUTH CRAM-MD5 authentication.
- Petri Kaukasoina wrote a little shared library which should help
qmail reliability
on Linux. Linux does not automagically fsync metadata
(information necessary tomake a file appear in the filesystem). It
only fsyncs metadata when the the directory is fsynced.
- Bruce Guenter's syncdir gives qmail bsd
fsync semantics on a Linux filesystem.
- Scott Moorhouse rewrote a patch (which someone had written earlier
and which I failed to publish here) to work around a Netscape bug, the
symptoms of which are that it does not know how big a message is, so
Netscape's download indicator
doesn't progress.
- Frank DENIS wrote a patch to truncate bounce
messages (local
copy, by author's request), on the off chance that the user may
have kept a copy of the email.
-
takeshi@SoftAgency.co.jp wrote MySQL +
QMAIL, including qmail-getpw-mysql and checkpassword-mysql, to
look up users in a mysql database. Iain Patterson has
improved on MySQL +
QMAIL.
- Also see sql-gpw and sql-cpw.
- Michael Devogelaere's qmail-sql now includes ODBC support.
- The prolific Bruce Guenter has written qmail-qfilter, which is
a front end for qmail-queue that can send the body of the message
through one or more filters, such as qmail-inject or new-inject.
-
Matthias Andree has a patch to allow qmail's sendmail wrapper to ignore the -N dsn
option that sendmail has, for compatibility with MUAs that use the
-N dsn switch (mutt can do)
- Russ Nelson updated his
changes to qmail-remote to send using
QMTP. If you wish to receive mail via qmtp, run qmtpd.
- Gerrit Pape has Debian packages.
- Klaus Reimer has code to change
the appearance of bounce
messages. Note that this has the potential to break QSBMF.
- Scott Woods has qmail running on
a Cray. It took some patching
to make it run on UNICOS, but it's running.
- Scott Gifford's moreipme
patch is available. This solves the problem seen when a host
has more IP addresses than it knows about. This happens in particular
when you have an IP masquerading load balancer in front of a host.
- Mark Delaney noted that he was getting spam with a
null envelope sender. That by itself is insufficient reason to reject
the email. However, when the spam has multiple envelope recipients,
it cannot be a bounce message. So, Charles
Cazabon wrote a patch to enforce single
recipients on bounces.
- André Oppermann
updated his ext-todo
patch, which solves the 'silly qmail syndrome'. That's where
qmail spends more time processing incoming email than scheduling
deliveries. You can get it with big-todo integrated as
big-ext-todo.
- Dr. Erwin Hoffmann has written
his own SMTP
Auth package.
- Bjoern Kalkbrenner has
improved the smtp-auth
client patch (alternate location) so it works with multiple users. This is of most
use for a desktop qmail installation which needs to relay mail through
a server that requires authentication. The original
author was Jay Soffian (documentation,
patch). Last
person to touch that patch was Robert
Sanders
- Giacomo Cariello has OpenBSD Qmail Ports, even though
Theo has removed them from portstree.
- Adrian Ho has increased qmail-remote's compliance with
RFC2821. Some smtp servers are now emitting 5XX responses from the
get-go, and mere RFC821 behavior doesn't deal well with them.
- James Raftery wants the canonicalized hostname in
