It looks like your Mailman list is configured in a sub-domain of your
copmpanies main domain. I'm assuming that means that email for the
mailing list is routed to the server hosting Mailman independent of your
main email server. Correct?

Okay. No from header modification.

What from address should receivers inside the organization see from
senders also inside the organization? Do they need to see the real
internal from header? Or is it okay that they see the mailing list address?
If it's okay that internal recipients see the mailing list instead of
the actaul internal senders, then the problem can likely be simplified
to be "internal senders should have their from address rewritten to the
mailing list address."

This almost sounds like an MTA masquerading issue. I don't know if
mailman can help with this or not. Especially if it's supposed to
conditionally happen based on the sender and the recipient.
