Thank you for your guidance. I created a new list. I'm able to subscribe and unsubscribe members to the new list. Emails are received when a member subscribes and unsubscribes to the new list. So, there are no issues with the relay host. However, when a message is posted, nothing happens.
I checked the /var/log/mailman folder. The following three files are updated as of today (16 Nov), and there isn't any clue as to why the lists are not receiving the postings. -rw-rw-r-- 1 list list 1432 Nov 16 16:44 smtp -rw-rw-r-- 1 list list 85623 Nov 16 16:44 subscribe -rw-rw-r-- 1 list list 9431 Nov 16 14:11 qrunner root@xxxx:/var/log/mailman# tail qrunner Master qrunner detected subprocess exit (pid: 2164, sig: None, sts: 15, class: VirginRunner, slice: 1/1) Nov 16 14:11:32 2023 (2621) CommandRunner qrunner started.

Create a new list with only your addresses as members. 2. Use one of the addresses to send mail to that new list. 3. Check your Postfix as well as mailman's logs for clues. It's inconceivable that you could not find anything in the logs.

I doubt if the SMTP Office 365 is the culprit because the list was running smoothly with the same SMTP relay host for more than a year!

I'm still on Mailman 2.1.26 on Ubuntu 18.04 with Postfix as an MTA. Till recently, the list was running smoothly. On average, there will be 2/3 postings every day. However, postings have not been received in the last two days. When I explored further, I noticed that postings made to the list are not reaching the list, nor are the members posting messages getting acknowledgements. I'm using SMTP Office 365 as the relay host. Generic emails sent from the Mailman server are getting distributed. So, there aren't any issues with incoming or outgoing emails. Mailman as service is up and running, and its service status is as follows: #service mailman status â mailman.service - Mailman Master Queue Runner Loaded: loaded (/lib/systemd/system/mailman.service; enabled; vendor preset: enabled) Active: active (running) since Thu 2023-11-16 14:11:31 IST; 30min ago Process: 2586 ExecStop=/usr/lib/mailman/bin/mailmanctl stop (code=exited, status=0/SUCCESS) Process: 2616 ExecStart=/usr/lib/mailman/bin/mailmanctl -s start (code=exited, status=0/SUCCESS) Main PID: 2617 (mailmanctl) Tasks: 9 (limit: 4915) CGroup: /system.slice/mailman.service ââ2617 /usr/bin/python /usr/lib/mailman/bin/mailmanctl -s start ââ2619 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=ArchRunner:0:1 -s ââ2620 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=BounceRunner:0:1 -s ââ2621 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=CommandRunner:0:1 -s ââ2622 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=IncomingRunner:0:1 -s ââ2623 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=NewsRunner:0:1 -s ââ2624 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=OutgoingRunner:0:1 -s ââ2625 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=VirginRunner:0:1 -s ââ2626 /usr/bin/python /var/lib/mailman/bin/qrunner --runner=RetryRunner:0:1 -s Nov 16 14:11:31 xxx.xxx.xxx.xx systemd[1]: Starting Mailman Master Queue Runner...

I looked into the log files but found nothing useful to resolve the issue. Can someone please help me to resolve the issue? The only plausible reason here is that SMTP Office 365 is the culprit. There is a discussion that happened in the Mailman3 lists that was related to Office 365 as a relay.
