I am experimenting with postfix notify_classes. To start the config is
notify_classes = bounce, 2bounce, data, delay, policy, protocol, resource, software Now in my postmaster inbox I received a message, Subject: Postfix SMTP server: errors from mailrelayus2-25.kubra.com[205.216.45.25] Transcript of session follows. Out: 220 tanzer.example.com ESMTP . No UCE permitted. In: EHLO mailrelayus2-25.kubra.com Out: 250-tanzer.example.com Out: 250-PIPELINING Out: 250-SIZE 104857600 Out: 250-STARTTLS Out: 250-ENHANCEDSTATUSCODES Out: 250 8BITMIME In: MAIL FROM:<[email protected]> SIZE=3492 Out: 250 2.1.0 Ok In: RCPT TO:<###@###.###> Out: 450 4.1.1 <###@###.###>: Recipient address rejected: unverified address: Invalid Address In: RSET Out: 250 2.0.0 Ok Session aborted, reason: lost connection For other details, see the local mail logfile I want to know which notify_classes class caused this error. I do not know which one just from reading the message. "reason: lost connection" does not immediately say to me which one. Can I add any logging configuration parameter to add the class that is generating this error for this message? So it is in the received email, without having to look into the logs?
