(Seeing as how I got away with it before I'll try it again.)
I think you are smashing two different aspects of a Mailman installation
together and trying to treat them as one. Namely the web interface
(hosted by a web server) and the mail interface (hosed by Postfix for
you). In my opinion these are two discreet and separate things that can
be dealt with as such.
(Seeing as how I run Sendmail, not Postfix, I don't know.) Is it
possible to configure Postfix to send any mail from a particular address
/ domain out via a specific interface? I.e. male *@list1.domain.tld go
out via IP 1 and *@list2.domain.tld go out via IP 2, etc.
Presuming that it is possible to get Postfix to route mail based on
sending address / domain, simply configure Mailman to smart host
everything out via Postfix and let Postfix decide how to handle the
messages. Thus Postfix will route email and Mailman will manage the
As far as your web server (I'm going to use Apache for discussion),
simply have Apache listen one all the IPs that are in use by the mailing
lists. Doing this will simply let you decide what you want Apache to do
with web requests. You can have separate web sites for each list if you
want, or you can do as you were saying and have the web site that
Mailman is running under available from all IPs.

I don't think that it is impossible. You just need to brake things up
in to their individual components and let them be handled by what ever
does them best. I.e. Postfix for email and Apache for web.
