I'm not sure I understand. Are you saying there is a group in Lotus
Notes which consists of the addresses of some Mailman lists and mail
to that group is sent to the Mailman lists and resent by Mailman to
the list members and is ultimately not delivered because the outgoing
MTA says 'user unknown'?

What happens when a post is sent directly to one of these lists, not
via the Lotus Notes group?
