Question What happened to verbose mail logging?

[Flachzange]

Server operating system version

Ubuntu 22.04.4 LTS

Plesk version and microupdate number

18.0.60 Update #1

I have an issue with outgoing email getting stuck in the queue and I wanted to debug as in the old days. I must admit I haven't looked at mail logs since a while now as the server was running smooth.

I am used to a super verbose syslog file in which I can see every connect and every incoming and outgoing email with all steps and filters applied.

However, syslog and maillog only contain now very few log entries for a few activities. How can I increase the log level back to something which I was used before? This affects multiple services and applications so I would assume there is somekind of central switch in Plesk.

For the issue at hand it would be already good to see the outgoing smtp connection.

Many thanks.

SMTP service: Postfix
IMAP service: Dovecot

Hi,

Have you tried `journalctl -u postfix` and `journalctl -u dovecot` instead of viewing a regular maillog file?

Gives me:

journalctl -u postfix
-- No entries --

I already applied https://support.plesk.com/hc/en-us/...5-How-to-enable-or-disable-Postfix-debug-mode
But this does not change anything although smtpd is definetely running with the v parameter.

I would expect log entries like this (just an example) : https://support.plesk.com/hc/en-us/...using-PHP-Scripts-bare-LF-received-after-DATA

What puzzles me is that it is not just postfix and dovecot. Also all spamassasin logs are missing. Basically everything for incoming and outgoing mail. I attached a maillog of today, which is basically empty except all these failed authentication attempts.

Appreciate your support

It seems I tricked myself a while ago: Resolved - systemd User Manager activity

This actually also had impacted the maillog. Reverting the changes and I have my logs back.
