I would use sendmail's mailertable feature for this. This requires:
* Sendmail 8.7.X (preferably 8.7.5)
* Procmail
Make sure you add the mailertable feature to your sendmail.cf file. Create
a file called /etc/mailertable with this line in it:
cc.csg.peachnet.edu procmail:/etc/procmailrcs/cc.csg.peachnet.edu
(Note, once you creat the text mailertable file, you need to make a hash of
it with a command like: 'makemap hash /etc/mailertable.db < /etc/mailertable'.)
This sets things up so that inbound mail to addresses @cc.csg.peachnet.edu
are processed through the procmail recipe file
/etc/procmailrcs/cc.csg.peachnet.edu. For example, you could insert
something like this into that file (this is a slightly modified version of
the really simply autoresponder from the procmailex man page; there is also
a more complex example that you can modify to suit your needs):
:0 h c
* !^FROM_DAEMON
* !^X-Loop: postmaster@cc.csg.peachnet.edu
| (formail -r -A"Precedence: junk" \
-A"X-Loop: postmaster@cc.csg.peachnet.edu" \
-I"From: postmaster@cc.csg.peachnet.edu"; \
cat /etc/autoreply) | $SENDMAIL -t
Theoretically, that should respond with the contents of the file
/etc/autoreply, but I haven't tested this to make sure I'm not an idiot and
telling you something completely wrong.
Mailertables are great. You can have all sorts of fun with them.
