  • What triggers these log lines? Is something that should be working not working? – anx Aug 07 '22 at 23:29
  • SSL logs are enabled for postfix; the trigger for these specific lines are TLS connections (receiving/sending mail) – tmclo Aug 08 '22 at 05:48
  • Consider asking this question on the Postfix mailing list, there you will usually get a competent answer quickly. – glts Aug 08 '22 at 12:11
