The threads I found out about the distribution lists were correct. I forgot (I
did set it up 10 years ago) that I migrated a manual disity mail list and
turned it into our OTRS system, so there was an OTRS user that was a member of
the original disty group that was still getting the mail.
Sorry about that. Hopefully people searching will find this useful.
