fetchmail is doing this. Just start it every 5 minutes with cron.
fetchmail pops the mails from the pop3 server and feeds it to the local
MTA which must handle mails for the domain correctly, of course.
I don't know if there is a simpler solution for fetchmail+mailman.

You probably have to check and possibly let sendmail rewrite header
fields correctly so that the From: etc. are correct.
AFAIK see now it should work if the mailman machine actually feels
responsible for the kirix.com domain as a whole (and perhaps for others
too) - it just doesn't receive mails from the eth<x> interface.
For local users you could forward local email to the pop-server via
Alternatively you could simply relay all outgoing mails of kirix.com
through the external mailserver and the external mailserver rewrites
header and envelope addresses.

The problem is not really a mailman problem (or closely related) but
more a "several MTAs problem".
