Good Afternoon,

I am having two challenges with Mailman and could use some guidance.
These two items are around message posting and re-enabling membership. 

1. I have a user that is not receiving the POST successful message. The
user submits a post and it is held to be released. The message is
released by the moderator and it goes out to all members successfully.
They received an email saying that either the message would be
distributed after approval by the monitor or that they would receive an
email saying why it was not. However, the poster did not receive a
confirmation that the message was successfully released or denied.

2. Regarding excessive bounces. I have a member of a list who was
disabled due to excessive bounces. They received the following email
(with items changed to protect identity):

Subject: confirm 0c56cb666666dad6c66666cb1f1dc1a11a0e666b1

Your membership in the mailing list name-of-list has been disabled due
to excessive bounces. The last bounce received from you was dated
02-Sep-2012.  You will not get any more messages from this list until
you re-enable your membership.  You will receive 2 more reminders like
this before your membership in the list is deleted.

To re-enable your membership, you can simply respond to this message
(leaving the Subject: line intact), or visit the confirmation page at


You can also visit your membership page at


On your membership page, you can change various delivery options such as
your email address and whether you get digests or not.  As a reminder,
your membership password is

If you have any questions or problems, you can contact the list owner at
    name-of-list-owner at list.informs.org

A. When they click on the above link they are getting the error:

Bad confirmation string
Invalid confirmation string: 0c56cb666666dad6c66666cb1f1dc1a11a0e666b1.

Note that confirmation strings expire approximately 3 days after the
initial subscription request. If your confirmation has expired, please
try to re-submit your subscription. Otherwise, re-enter your
confirmation string.

B. In addition, if they try to respond to re-enable via email they get
the following message:

From: Mail Delivery System [mailto:MAILER-DAEMON at email_address]
Sent: Tuesday, September 11, 2012 12:37 PM
To: email_address
Subject: Undelivered Mail Returned to Sender

This is the mail system at host server_name.

I'm sorry to have to inform you that your message could not be delivered
to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.
If you do so, please include this problem report. You can delete your
own text from the attached returned message.
