For Postfix integration, you need to do a few things.

Consider only the one mailman instance for the domain example.com. The
others will be analagous.

in mm_cfg.py, add

POSTFIX_STYLE_VIRTUAL_DOMAINS = ['example.com']

This will cause mailman to also write data/virtual-mailman with entries
like

list at example.com        list
list-admin at example.com  list-admin
...

in addition to data/aliases with entries like

list:       "|path/to/wrapper post list"
list-admin: "|path/to/wrapper admin list"
...

for each list. The data/virtual-mailman(.db) is analagous to Ashley's
/etc/mail/virtusertable.

There is still a problem in that there is a potential list name
conflict, so to resolve that, you need to make a patch (see attached
Postfix.patch.txt) to Mailman/MTA/Postfix to make virtual-mailman and
aliases look like

list at example.com        list.example.com
list-admin at example.com  list-admin.example.com
...

and

list.example.com:       "|path/to/wrapper post list"
list-admin.example.com: "|path/to/wrapper admin list"
...


Then you need the following in Postfix's main.cf

alias_maps = ...
   hash:/path/to/example.com's/data/aliases


virtual_alias_domains ...  example.com

virtual_alias_maps = ...
   hash:/path/to/example.com's/data/virtual-mailman

And probably also if you don't have them anyway

recipient_delimiter = +
unknown_local_recipient_reject_code = 550
