Hi there.
Just as a warning, I'm new to the list, and have a question. I tried
to check the FAQ and archives for the answer, but my lack of
mailer-term knowledge stimied me. So, apologies if this question was
asked before, but I don't know how to describe it.
First, some background: We run a Novell file server, and use Mercury
mail for our POP system. Mercury, in case you don't know, is
SMTP-stupid...anything non-local it passes to a specified SMTP-aware
system to deliver. Since our Novell admin knew the IP of another
SMTP-aware box at the university, no problems.
Until one morning when the admin of the other box decided that our
department shouldn't be allowed to deliver.
We were using a small 486 running Linux as our webserver at the time,
running the sendmail that was installed with it. (Slackware 3.5, I
think). In desperation, we pointed the growing backlog of mail at the
webserver. Amazingly, it cleared out the backlog in 8 minutes and
served quite dutifully, despite some immense files thrown at it.
[What this says about the security of sendmail I'll ignore for the
moment].
Anyway, in time we upgraded the Linux box to RedHat 5.2 on a PentiumII
450. Now that I was a slightly more experienced Linux administrator,
I tried to increase some security...xinetd, etc...including qmail.
All was well and good, but as time passed it became obvious that it
was more effort that it is worth to maintain two separate linux boxes
of two distributions when the one box can do everything. So we want
to repeat our trick.
My question (finally!): How do I configure qmail to send mail routed
to it from another host? Without messing up delivery by qmail for
messages generated from the same box?
Example: www.example.edu is running qmail on Linux.
other.example.edu is running Novell w/Mercury.
POP messages are sent to other.example.edu as they currently do.
other.example.edu delivers any local messages, while sending any
non-local messages to www.example.edu to be delivered.
www.example.edu accepts any messages from other.example.edu and does
the lookup/delivery to wherever. (incoming messages from other hosts
will go directly to other.example.edu) At the same time, the web
server on www.example.edu will send messages to wherever as well
(using qmail), which it does now and which I have no desire to break.
Thanks for any help in advance. I am totally new to mailer
administration, so if this has been answered at length you can just
point me in the right directions with some terminology help.
BTW, we attempted to simply "point" as we did before, but the mail did
not deliver. I'm afraid I don't have the log entries on hand, but if
it is helpful (i.e. it should work without special configuration) I
can get with our Novell admin and repeat the test.
