I would run swaks from the same box on which you run Mailman, and use -f
with whatever Mailman uses as the envelope sender address for posts,  If
you have VERP personalization turned on, this would be a "bounces"
address.  Send to a sample (test) address that's on the list, and use -s
with the FQN of the server which your Mailman installation uses.

All of this assumes, of course, that you're using postfix as a SMTP
server (DELIVERY_MODULE = 'SMTPDirect' as opposed to
DELIVERY_MODULE='Sendmail').  If you're using the latter, then swaks
won't help you.

BTW, it would be a good idea if you'd cc questions such as this to the
list.  There are some very good minds on the list who might well chime
in helpfully, and/or critique my response.
