I need to go look at my new postfix machines to make sure those aren't happening there. Those machines have mail_version = 3.6.4 Time to look in the docs to see if that's turned on. -----Original Message----- From: owner-postfix-us...@postfix.org <owner-postfix-us...@postfix.org> On Behalf Of Wietse Venema Sent: Friday, February 10, 2023 12:34 PM To: Postfix users <postfix-users@postfix.org> Subject: Re: missing log entries for old version of postfix Sean Hennessey: > I have a machine running a very old version of postfix.

All three messages were queued at the same time, 12:59:58, and were delivered between 13:00:03 and 13:00:06. All three messages would have produced cleanup logging and qmgr logging at the time that the messages were queued. These are missing: postfix/cleanup[pid]: queueid: message-id=<pattern> postfix/qmgr[pid]: queueid: from=<sender>, size=nn, nrcpt=nn (queue active) Most plausible explanations: - The logfile was rotated between 12:59:58 and 13:00:03. - Your systemd is throttling Postfix logs, and threw away the logging that was generated around 12:59:58. This is one reason why I implemented direct-to-file logging in Postfix 3.4. Wietse
