Mailman discards posts with no clue as to why

jndawson
We've been working on this issue for a couple of days. Customer has long-running mailing list with one weekly post by him. Suddenly, after several years, his post gets discarded. We've run /scripts/fixmailman and /usr/local/cpanel/bin/mailman-install --force with no errors. Examples: /var/log/exim-mainlog:
2016-02-15 18:06:35 1aVV2A-0008Nm-W9 <= customer@customer.tld H=mx.domain.com [111.222.333.444]:26132 P=esmtps X=TLSv1.2:ECDHE-RSA-AES256-GCM-SHA384:256 CV=no S=3913 id=EEAB113E-035B-4FC2-95AD-26627283B38C@customer.tld T="Subject" for listname@customer.tld 2016-02-15 18:06:35 1aVV2A-0008Nm-W9 => listname R=mailman_virtual_router T=mailman_virtual_transport
/usr/local/cpanel/3rdparty/mailman/logs/vette:
Feb 15 18:06:35 2016 (19397) Message discarded, msgid: ' list: Listname, handler: Moderate Feb 15 19:03:47 2016 (6313) Message discarded, msgid: ' list: Listname, handler: Moderate
In all cases, the post is discarded and no other notice or action is taken. We've attempted 2 or 3 different hacks found on various mailman and python forums to /usr/local/cpanel/3rdparty/mailman/Mailman/Queue/IncomingRunner.py and /usr/local/cpanel/3rdparty/mailman/Mailman/Handlers/SMTPDirect.py to increase reporting level, but mailman either chokes, throws errors, or has no affect. No other mailing lists are experiencing the issue.

    Hello :) Is moderation for the sender enabled under "Membership Management" in Mailman? Thank you.

    Hello :) Is moderation for the sender enabled under "Membership Management" in Mailman? Thank you.

    Yes. The list owner is the only sender and hasn't changed any settings after having operated the list for several years.

    You can disable moderation for the sender, to ensure it goes straight through without requiring approval. Could you let us know if that addresses the issue? Thank you.

    1. Why would mailman suddenly change behavior after several years of using the exact same settings? Has cPanel changed something? 2. Why do you think that disabling moderation will prevent discards since the discard function occurs prior to sending to moderation?

    Could you open a support ticket using the link in my signature so we can take a closer look and determine why this behavior is occurring? Please post the ticket number here so we can update this thread with the outcome. Thank you.

    To update, it looks like the issue is no longer occurring after removing the moderated flag for the admin user. Feel free to let us know if any additional issues persist. Thank you.

    To be more correct, it looks like the issue is no longer occurring after we got the customer to stop messing around with his settings while we were testing. Thanks to the patient and diligent techs that helped to trouble shoot.
