Hi Odhiambo, Thank you for the reply. 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.
