[Mailman-Users] trouble with unsubscribed user

[Doug Garaux]

I have a MM 2.1.5 install that I've had various troubles with.  The list
was manually transferred from another ISP to a new dedicated server
environment.  I was unable to transfer the list by documented methods
since I could not access mailman command from a unix shell so I created
the list on the new server and manually dumped all the users from the
old list and mass subscribed them on the new server.  As most of the
users don't configure their own settings it was a good enough trade off.
I however have had a few issues.  One is a bounce I receive for a
invalid email (invalid user at site..)  I manually unsubscribed the user
but MM is still sending emails to this email address.  I have no clue
why as I don't see the email under membership management in the web GUI.
The other issue I've had is with the users who were not required to be
moderated.  I have unset the moderation box for one email so they do not
have to approve (their own) emails when they post but MM is still asking
for all of their (and all others which is correct behavior there) to be
moderated.  How can I verify that this users posts are not requiring
moderation?
The settings from the webgui are basically identical from old server to
new server.  The only difference I know of is the old server was a
CPANEL installed mailman instance and the new server is a PLESK
installed instance of mailman.
Thanks!
