Hi,
we are running MM3¹ and from time to time, a mail to a mailing list is not processed by MM. MM sees the mail but still does nothing with it. If another user is sending _same_ mail, it is processed.
Any idea what that could be? Here are some logs:
Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) handling connection Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'LHLO mal01.mydomain.tld' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'MAIL FROM:<john.doe@mydomain.tld>' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) sender: john.doe@mydomain.tld Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'RCPT TO:<ssa@mydomain.tld>' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) recip: ssa@mydomain.tld Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'DATA' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) Data: b'QUIT' Apr 27 13:02:13 2022 (1919) ('127.0.0.1', 44800) connection lost
Here is a snipped from same user, but different mail that is also not processed by MM:

Any help is greatly appreciated. Thank you.
