Re: spam deferring engine

Looked this over and I think you have hit on a great idea.

Every OpenBSD box will become part of a giant, self-inflicted Distributed denial of service "attack" against the open relay machine. Even a well connected machine can be impacted if the number of boxes using this approach gets big enough. I wonder if you could do anything useful by turning the connection around and sending a gift to postmaster? Don't remember all of the rules for that part of the protocol.

I wonder about the stutter. I know that the "tar pit" idea is pretty well known but I don't know if your approach may be better off by getting them in and out fast. I know the process is light-weight but a large Spam volume could still keep your box busy when it does not need to be. Will have to give this some thought. Received on Fri Dec 20 00:08:34 2002
