	In my own highly-hacked version of mailman that I use, I do this. 
Mailman simply drops outgoing messages into the queue directory. A
background daemon de-queues the messages and pumps them to the local MTA
via SMTP. A cronjob checks the  daemon periodically, and starts it if is
falls over. All very simple, and  has worked very reliably for me for
several months.
