[Mailman-Users] Configuring Mailman with Postfix and Postfix Admin

[NSHB]

I have just setup Mailman 2.1.5 on FreeBSD 4.8 and have found that the
installation does not integrate by default with the postfix admin which
stores all users and domains in MySQL.

When I send an email to the list I successfully setup, I receive this error:

Your message did not reach some or all of the intended recipients.
    Subject:             test

The following recipient(s) could not be reached:
     'mailman at inimit.com' on 22/08/2004 5:01 PM

550 <mailman at inimit.com>: Recipient address rejected: User unknown in
virtual mailbox table

How might I be able to integrate the mailman python script to filter out the
mailman users into my setup?

Regards,
Nathan.
