I have an issue with Ubuntu 14.04 server.

The issue is that the /var/log/mail.log is getting huge and its saturating the server.

My question is: is there a way to do some automatic log rotating so I can limit the log size to some reasonable size?


The default application to do that is logrotate. The config file has some examples on how to rotate. But something like this:

    rotate 7
        reload mail.log >/dev/null 2>&1 || true

for a 7 day rotation.

But! Do have a look at your mail.log and see if what is put in there is not an ERROR or someone abusing your system as a relay to send out spam.

  • Yes you where right , we had nonworking smtp server that caused the log to accumulate – user1289947 Mar 7 '16 at 14:39

  • logrotate uses its own daemon. – Rinzwind Mar 7 '16 at 14:44
  • logrotate usually installs its own cron file in /etc/cron.daily/logrotate, so runs daily by default. – meuh Mar 7 '16 at 16:01
