(Note:  This may very well be an "open mouth, insert foot" reply, but 
I'll do it any way.)

It is my (mis)understanding that Mailman sends email to the local MTA 
which then sends the emails on out to the world its self, not Mailman. 
(Though this may be a configuration option, hence the phrase above.)

Presuming that my (mis)understanding is correct...  This is more of an 
MTA option rather than a Mailman option.  The closest that I can think 
of for Mailman would be to have each list use a different MTA (bound to 
different IPs).  That way each MTA (thus lists using said MTA) would 
send it's messages out from its own IP.

Can someone else please confirm or correct me on how Mailman is 
operating with regards to the MTA?

What MTA are you using?  If it's Sendmail I might be able to help you 
get it to behave like you are wanting.
