[Mailman-Users] Recipe for (mailman+postfix) <-> exchange?

[Morgan Fletcher]

Hi. I work at a small company with an externally hosted Exhange server 
for an MTA. DNS is also externally managed. We'd like to set up mailing 
lists and I'd like to use Mailman to do it. We have a linux machine 
internally on which I've installed Mailman & Postfix. I can configure 
this machine to be aliased lists.domain.com and get our local name 
server to make it available as such. What else do I have to do to get 
mail from and to lists.domain.com via Exchange? Some list members would 
be within our company network, some would be external. We'd make the 
necessary ports on lists.domain.com accessible to the outside world.

I apologize if this is an inappropriate request. I'm hoping someone here 
has done this and would be willing to share their recipe. I can share 
mine once it's working.
