Mailman 2.1.35 on cPanel version 98.0.12

The list is set to only accept messages from subscribers

Action to take for postings from non-members for which no explicit action is defined (Details for generic_nonmember_action) is set to "Hold" I receive a notification when someone tries to post using a non-subscriber address.

The non-member receives this message (message #1):

Your mail to 'Infoline' with the subject

    Test non-member

Is being held until the list moderator can review it for approval.

The reason it is being held:

    Post by non-member to a members-only list

Either the message will get posted to the list, or you will receive notification of the moderator's decision.  If you would like to cancel this posting, please visit the following URL:

I (as the owner of the mailing list receive the notification (message #2) stating:

As list administrator, your authorization is requested for the following mailing list posting:

    List:    Infoline@xxxxx.ch From:    macchristian@xxxxx.ch Subject: Test non-member Reason:  Post by non-member to a members-only list

At your convenience, visit:

    http://mus.ch/mailman/admindb/infoline_mus.ch to approve or deny the request.

One attachment to the notification is a message (message #3) with the subject "confirm d1c110e1babc8c9b34cd40a17c0ab8e0770e8617" which tells me:

If you reply to this message, keeping the Subject: header intact, Mailman will discard the held message.  Do this if the message is spam.  If you reply to this message and include an Approved: header with the list password in it, the message will be approved for posting to the list.  The Approved: header can also appear in the first line of the body of the reply.

Okay, I reply to the message. In earlier times, I got a response that the message was sent into the Nirvana - or that the user had deleted it himself using the link he received in message #1

However something seems to be broken now.

• The held message is no longer deleted when I reply to the "confirmation".
• I no longer receive a notification that the message was no longer on hold.
• The message remains in hold, even after the "confirmation" was replied to.

Yes, I can manually "reject" or "discard" the message.

My provider says he has no knowledge about how Mailman on cPanel works, and I should ask in Mailman-related forums / lists...

Any idea how it can be fixed?

Thank you, Christian
