   I have done this with great success.  I must be brief as I'm in a  
rush, but here's the basic overview:

   - Create a new transport in master.cf, I called it "mailman".  It  
looks like this:

-------------------
mailman   unix  -       n       n       -       -       pipe
   flags=FR user=mailman:nobody
   argv=/usr/local/mailman/bin/postfix-to-mailman.py ${nexthop} ${user}
-------------------

   The "postfix-to-mailman.py" script can be found via google.  I had  
to make some minor changes to the one I found; I can send you mine if  
you get stuck.

   - Create a "pseudo-subdomain" (not in DNS) for Mailman, I used  
"lists.<domainname>".

   - Set the transport for the "lists.<domainname>" to be "mailman:"  
in your transport map.

   - Rewrite all relevant "<listaddress>@<domainname>" addresses (- 
admin, -request, etc) into the "lists" subdomain of the form  
"<listaddress>@lists.<domainname>" using virtual aliases.

   If you run into trouble, contact me off-list and I'll try to help.
