I am getting "too many reverse jump records" messages. Couldn't find any information about this message and looking at the source code (record.c) it seems to be related with adding recipients and/or headers, but I am not adding that many (10000) of either.
There is a milter application before queue that adds a couple of headers but that is it. Between start and the final delivery there were 509 of these warnings (delays=3548/4125/0.24/0.49). This is a very active server and usually there are a few thousand mails in the queue. 2021-07-13T15:26:14.777532+00:00 server01 postfix/smtpd[912469]: 4GPKc12345z6n5pV: client=unknown[10.11.22.33], sasl_method=XCLIENT, sasl_username=u...@redacted.com 2021-07-13T15:26:14.827403+00:00 server01 postfix/cleanup[910108]: 4GPKc12345z6n5pV: message-id=<i3sb59ki3vilfcdmrq9iure84...@server.redacted.com> 2021-07-13T15:26:15.769603+00:00 server01 postfix/showq[785453]: warning: incoming/4GPKc12345z6n5pV: too many reverse jump records 2021-07-13T15:26:30.822828+00:00 server01 postfix/showq[785453]: warning: incoming/4GPKc12345z6n5pV: too many reverse jump records 2021-07-13T15:26:45.635767+00:00 server01 postfix/showq[785453]: warning: incoming/4GPKc12345z6n5pV: too many reverse jump records ... 2021-07-13T16:25:29.736077+00:00 server01 postfix/showq[1285034]: warning: active/4GPKc12345z6n5pV: too many reverse jump records 2021-07-13T16:25:44.793480+00:00 server01 postfix/showq[1285484]: warning: active/4GPKc12345z6n5pV: too many reverse jump records 2021-07-13T16:25:59.764867+00:00 server01 postfix/showq[1285034]: warning: active/4GPKc12345z6n5pV: too many reverse jump records ... 2021-07-13T17:34:06.914021+00:00 server01 postfix/smtp[1788437]: 4GPKc12345z6n5pV: to=<u...@rctpdomain.com>, relay=rcpt.server.com[10.12.23.34]:25, delay=7673, delays=3548/4125/0.24/0.49, dsn=2.0.0, status=sent (250 2.0.0 Message accepted for delivery) 2021-07-13T17:34:06.915500+00:00 server01 postfix/qmgr[1283513]: 4GPKc12345z6n5pV: removed Thank you -- Mehmet
