There is no mail.log anymore, it is written to the journal with Debian12 - see e.g. here: https://think.unblog.ch/en/debian-12-no ... ournalctl/

If you want it back, install rsyslog.

OK,Thanks every friend for my answer.
But I want know why no mail traffic.I has see incoming mail and outgoing mail.But it's always show zero.

Traffic, databases and webspace are not calculated in realtime.

Database and webspace are updated every four hours and traffic once at night.

Have a look into the settings of "Maintenance Intervals -> Update statistics".

Default is, it runs once every day around 00:00 -> 01:00 o'clock.

[akong77]

I has manual run update statistics.But it's show zero.

Please activate support access (Configuration -> Support Access) and send me the server IP and SSH port via PM.

The problem is fixed on the server and will be fixed in an upcoming update for affected servers.

Background:

For calculating the mail traffic, i use journalctl. After the traffic calculation is run for the first time, i only read the new logs. Journalctl has a system called "cursor" for this. The cursor specifies the location within the log (journalctl).
When the traffic calculation has not yet run, i don't have a "cursor", so i read the journalctl from the beginning, using the "--since" parameter. I used "--since=1970-01-01 01:00:00" for that. It turns out, that this is transferred to the time zone on the server (UTC+0800), and so it can be negative.
Journalctl would than complain about an invalid timestamp and not returning any results, and therefor no result were returned to calculate the traffic.

I have now modified the --since parameter value so the issue is fixed.

OK,Thanks for your reply and help.
Could it's my setup error or another question?

[Alexander]

No, your setup is fine. It is a bug in KeyHelp 24.2, which could affect servers with a time zone setting >= UTC+0200.

[akong77]

OK,Thanks a lot.
