Hi.
I am having a hard time understanding how to set up qmail to stop third-party relaying
while still accepting all of the legitimate mail our users recieve.
The specific problem I have having is that mail from distribution lists (where the To:
field addresses the list itself and not that of the local user) is being seen as a
relay since the list domain isn't in /var/qmail/control/rcpthosts and tcp-env isn't
setting RELAYCLIENT because the list domain is also not in the set of domains we want
to accept relays for.
I read and reread the FAQ but didn't see an answer for this situation. It seems like
it would be a common problem, but perhaps I just don't understand enough of how the
qmail system works.
Thanks in advance for any help.
