This is, as you say, off-topic, so if you choose to respond to me, you
should probably do so off the list.

In other words, relaying doesn't work. What I mean is, if someone
logs into your SMTP server (through IMAP or otherwise!) and tries to
send mail to a machine other than the localhost, qmail freaks out.
Right?
The accepted fix for this is to run qmail-smtpd through ucspi-tcp
(specifically, tcpserver) and set the RELAYCLIENT environment variable
if the connecting client is someone authorized to relay mail through
your server. This is what I use; it works fine, though it's not what
I'd call easy for newbies to setup.
Or, you could put every host any of your clients will ever send mail
to in the file /var/qmail/control/rcpthosts. This is almost never
practical.
The final "fix," used by a disturbing number of sites, is to turn off
RCPT host checking (rm /var/qmail/control/{,more}rcpthosts), so all
mail to/from anywhere is accepted by your server. If you do this, you
*will* be used as a spam pipeline, and because of this, mail through
your site *will* eventually be rejected by many hosts.
If you've tried to setup some solution and failed, please send me a
little more information, and I'll try to help sort it out. Failing
that, there's a qmail-specific mailing list that might help, too. As
I've implied, I'll bet this has nothing to with your IMAP setupu.
qmail's a great program, but getting it setup properly (in a
non-trivial environment) requires a certain mentality.
