Actually you don't. Mailman talks to sendmail at the SMTP level, not at
the sendmail command level and it specifies it's own domain
(configured in Mailman) in both From: and envelope sender.

If you run Sendmail on your server so it listens on 'localhost' port
25, Mailman will talk to it 'out of the box'
I'm not fully familiar with Fetchmail's capabilities, but if Fetchmail
can retrieve mail from a remote mailbox and pipe it to a local command
(different depending on which mailbox it came from), this will work.
Also, Procmail can definitely do what's required to get mail to
Also, there is another 'experimental' way to get mail to Mailman where
Fetchmail would deposit the incoming mail in a local directory, and
Mailman's USE_MAILDIR option is set so Mailman basically polls the
local directory for new mail.

You would set up Mailman to know and use the external domain names.
There are some potential complications mostly involving what list
names appear on what web pages, but as long as you are not trying to
support multiple domains with some lists in one and other lists in
another, these are easily handled.

I'm not sure what you are envisioning here, but I think there is no
problem. I think everything can use 'outside' addresses.
