Is that what you really need, or is this a way to accomplish some other goal?

SMTP AUTH/TLS is to the server, and the server cares not if it is the destination, or simply a hop along the way.

For testing and boredom relief, I setup

• My laptop uses TLS/AUTH betwixt the MSP and MTA on localhost which then uses TLS/AUTH to connect my home server and TLS to talk to other MTAs
• My home server accepts, but does not require TLS/AUTH for local lan connections, but requires TLS/AUTH for port 587 and uses TLS/AUTH to talk to my ISP, but only TLS when talking to other MTAs. Add dk/dkim to the mix, and it easy to have most of your mails wind up with more headers than body :)

You can control what the MTA requires and/or allows for each connection it answers, or it originates (based on DNS fqdn, IP, CN, etc.)

You can do all of this with the access and/or authinfo databases just make sure you have FEATURE(`authinfo')dnl in sendmail.mc

install, if you've not already, sendmail-doc and peruse /usr/share/doc/sendmail/cf.README.gz, especially the section 'SMTP AUTHENTICATION' http://www.sendmail.org/~ca/email/auth.html has a decent walk-through on setting this up and debugging it.

 it's weird, when you go on a safari to Africa to catch a lion, you
        find it alive and it charges, and then you kill it
 when you go on a safari to South Bay to find a Palm Vx, you find
        it dead and take it home and it charges after it arrives :)
