This is really a Postfix question, not a Mailman question, but
postfix_to_mailman.py is designed to work with a dedicated domain
which receives all and only Mailman list mail.

There needs to be an entry in Postfix's transport_maps specifying a
'mailman' transport for that domain and an entry in Postfix's
master.cf defining that transport as a pipe to postfix_to_mailman.py.
