Isn't /var/log/maillog an smtp-level log? I'm under the impression
that it has nothing to do with mailman in particular. I'm mentioning
this because as I said in a previous message, it seems like mail isn't
even reaching the system because when I send mail directly to a user
account on that system, there is no record of such a message in
/var/log/maillog. Likewise, there's no record of anything when I send
to a mailman list.

My smtp logs only contain outgoing messages sent by crond -- nothing
incoming. I don't have a smtp-failure log. Is the maillog the MTA log?
If not, where is the MTA log?

My server is behind a router and SMTP's default port is 25. Therefore,
I've forwarded incoming requests on port 25 to the server. However,
there may be something else I need to do to get incoming mail to be
recognized.

My MTA is a local sendmail install. How do I increase debugging support?

Note that the only way I can get an incoming mail entry to show up in
maillog is if I send mail locally on the system from, say, root to
foo, where foo is a non-root user on the same system. Otherwise, I see
nothing at all.

So, unless I'm missing something, it looks like my problem is
independent of mailman.

Does anyone have suggestions?
