I'm not an "MTA expert," either.  However, I've used sendmail ever
since there was a sendmail.  My systems are Solaris, which comes with
a good implementation of sendmail, and my installations are all
configured to do what I want them to do with regular e-mail.  

I found adding Mailman to my existing setups to be quite simple.
You'll need to manually add the Mailman pipes to the aliases, using
the Mailman utility that gives you the list, but with the vi editor,
it's a simply copy-and-paste.  The only issue I had with integrating
Mailman with sendmail was getting the Masquerades set up properly to
host a different domain on my systems.  however, that is covered in 
the O'Reilly "Bat Book," which you should have.  It is not a Mailman
issue, and proper configuration is done through the M4 macro files.  
I haven't had to tamper with the sendmail.cf file separately.

I think that if you're familiar with sendmail, and have a satisfactory
setup, do your upgrade, and integrate it with your current sendmail.
I'm aware that most of the people posting to this list are using other
MTA's on Linux systems, so there's little support here for a sendmail

For reference, my links between Mailman and sendmail are through
localhost to a local sendmail, and I also have a caching DNS server,
all on the same box.  

For me, switching to another MTA would mean a lot of work learning how
to integrate all of the spam filtering and other things I already have
integrated and working in sendmail.
