I have a host that has 2 names (for example hosta.dom.ain, hostb.dom.ain),
because of a migration, and users refusing to update address books, both
names will remain valid forever.
This box runs mailman, and the mailman aliases are picked up with the mailman
router/transport as in README.EXIM from the mailman docs for 2.1.5 (this is
Exim 4.50 from FreeBSD ports, as well as Mailman 2.1.5 from FreeBSD ports).
What's happening is if someone replys to all to a post to hosta.dom.ain (the
original name), both names (list@???, list@???) appear in
the to:/cc: headers, and duplicate messages are received.
How can I make it so Exim will only deliver ONE copy of such a message to the
Mailman router/transport?
