Toolkit to manage spam and virus quarantine, and send spam report mails.
The possible timespans are week, yesterday, and today. The default pmgspamreport.service is run at 00:05 every day and calls the pmgqm command with the --timespan yesterday parameter. This will send a spam report if at least one new spam mail was moved to the quarantine since the beginning of the previous day.
The service can be edited, for example, to change the timespan to today or week, with the following command:
systemctl edit pmgspamreport.service
The timer can be edited with the command below:
systemctl edit pmgspamreport.timer
Note that adding another OnCalendar event will cause the report to be sent in addition to the default time. If you want to prevent the default email at 00:05, you must first reset the original OnCalendar setting, For example, to send the emails only at 06:00 you would enter the following lines when editing the timer unit:
[Timer] OnCalendar= OnCalendar=06:00
For details see the systemd man pages: systemd.unit(5), systemd.timer(5).
