The installation notes say you must have some form of MTA running on 
the machine running Mailman to deliver incoming posts to Mailman's 
delivery script(s). Mailman is quite agnostic about what that transfer 
agent should be and any one of a number of MTAs can be used; see the 
READMEs in the source distribution.

If your main mail server and the mailman server used NFS to give both 
access to the file space Mailman uses then it might be possible for 
your Mail server to inject messages directly into Mailman's queues but 
this is not a configuration I have (yet) attempted but another reader 
of the list may have done; if so, please step forward.

It is simple configuration matter for Mailman to pass outgoing mail 
direct to an SMTP server on a machine other than the one it (Mailman) 
is running on. But what do you mean by 'require authentication for 
outgoing mail' in what you said above?

As a sanity check, the main site I manage Mailman for does not expose 
the Mailman server to the internet. All incoming (and outgoing) mail 
goes through dedicated mail relay machines that do the site's virus and 
spam checking on incoming and outgoing mail. The Mailman server's local 
MTA just gets and passes 'clean' incoming posts to Mailman from the 
site's mail relays.
