[Mailman-Users] One List Not Receiving Mail

[Tapia, Rene]

Good Afternoon,

I am new to the Mailman application, but was tasked to migrate the application (data) to a new server. I completed the task and am now running Mailman version 2.14. Everything seems to be working fine, except for one LIST. I thought it was due to the migration, but the user reported that the issue has been ongoing for a few months. Anytime the user sends an email to the list, the email flows correctly all the way to the POSTFIX on the mailman server. From the logs I see that Postfix executes (delivered to command: /usr/lib/mailman/mailman listname). That is where any logs for that LIST stops. I check the archives and pending moderator requests, and nothing is in there. Once again, this is just for one list. All the other lists work fine.

I have tried to send myself and have verified the person is set to send mail. Everything dies after that Postfix command. Can someone please help or advise on how to fix/find the issue? Any help is appreciated.

Thanks,
René Tapia
