Shawn,
Well, in that case, I'd recommend you try using relay-ctrl-allow (and
the companion package relay-ctrl-age). Together, these two allow you
to authenticate a user (e.g., via POP3), and then include the
dynamically assigned IP address in the list of "OK to relay" hosts.
The relay-ctrl-allow package takes care of adding the
(just-authenticated) user to the appropriate CDB which tcpserver checks
before passing the SMTP connection to qmail-smtp. This is where the
modular beauty of tcpserver + <authentication> + relay-ctrl-allow +
qmail-pop3d, really shines.
This is an excellent way to allow people to use your SMTP server as a
relay, but to retain control of the relaying. In other words, you have
to authenticate via POP3 before you are allowed to relay. (That send
and receive button just came in handy, eh?)
It may take some digging around to find some good examples of
relay-ctrl-allow and relay-ctrl-age scripts, but I'm sure there are
others on the list who would be glad to help with that...you should be
able to find exactly what you are looking for in Bruce Guenter's RPMS,
which you should be able to locate somewhere from http://www.qmail.org/.
Good luck,
-Martin
