Recipe for (mailman+postfix) <-> exchange?
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.

This sounds to me like an Exchange problem. I'm not sure we can help you there.
If you wanted to run Mailman with postfix on a publicly accessible system, that's a very well known and supported configuration -- we do that for all the mailing lists hosted here on python.org, including this one.

Please let us know what kind of success you have. We can't really officially support such configurations, but it doesn't hurt us to have more information we can provide to people when they ask about them. At the very least, it can be handy for us to know where to point people when this question comes up again.

Can the Linux machine communicate directly with the internet at large?
If not, most of this is Exchange configuration. I.e. Exchange needs to route incoming mail to the lists.domain.com domain to the Linux machine. This may require an MX record to first route mail to lists.domain.com to the Exchange server, and something to tell exchange where to send this mail.
Also, Postfix will need to be configured to route all mail to the Exchange server and Exchange configured to relay mail from the Linux machine.
OTOH, if the Linux machine can communicate with the internet, it seems you can bypass Exchange alltogether and let the Linux machine handle its own incoming and outgoing mail.
