I noticed that my mailman logfiles are not being rotated. I followed the instructions in

https://mail.python.org/archives/list/mailman-developers@python.org/message/

Those instructions are for Mailman 2.1.

Now when I try and run logrotate I get the following error

root@zarathustra:/opt/mailman/mm/logs# logrotate /etc/logrotate.conf error: stat of /opt/mailman/mm/logs/bounce.log failed: No such file or directory error: stat of /opt/mailman/mm/error.log failed: No such file or directory error: stat of /opt/mailman/mm/mailman.log failed: No such file or directory error: stat of /opt/mailman/mm/mailmansuite.log failed: No such file or directory error: stat of /opt/mailman/mm/smtp.log failed: No such file or directory root@zarathustra:

What am I doing wrong please?

Here's a logrotate script I use:

/opt/mailman/mm/var/logs/*.log {
     missingok
     sharedscripts
     su mailman mailman
     postrotate
         sudo -u mailman /opt/mailman/mm/bin/mailman reopen  &>/dev/null
|| true
         if [ -r /opt/mailman/mm/var/gunicorn.pid ]; then
             PID=`cat /opt/mailman/mm/var/gunicorn.pid`
             kill -s USR1 $PID
         fi
     endscript
}

A couple of caveats. The first line of the postrotate script may be wrapped. sudo ... true is all one line.

That line could also be

/opt/mailman/mm/bin/mailman --run-as-root reopen  &>/dev/null || true

I.e., it either has to run as the mailman user or specify the --run-as-root option.

Also, if logs aren't in /opt/mailman/mm/var/logs/ or gunicorn.pid isn't in /opt/mailman/mm/var/ those paths need adjusting.

Finally, there may be an issue with mailman reopen in the postrotate scrupt. See https://gitlab.com/mailman/mailman/-/issues/1078

In my case, I took a different approach with Django's logging configuration: [snip] 'handlers': { 'file': { 'level': 'INFO', 'class': 'logging.handlers.TimedRotatingFileHandler', 'filename': '/opt/mailman/mm/var/logs/mailmanweb.log', 'when': 'D', # specifies the interval 'interval': 1, # defaults to 1, only necessary for other values 'backupCount': 5, # how many backup file to keep, 5 days 'formatter': 'simpleRe', }, }, [snip]

I have not been rotating the other log files as my list is not a high-volume one so logs aren't growing much. Plus I only rely on the logs for diagnostics, not for records ;(
