PROBLEM
My Atmail logs are growing too large.

ENVIRONMENT

• On-Premise Server + WebMail Installations: Version 6.0 > Current Version
• Webmail Only Installations: Version 6.0 > Current Version

CAUSE

Configuring Logrotate is critical, so as to reduce the size of the files used by Atmail in the webmail/log directory. To implement logrotate for your server, please do the following:

RESOLUTION

1. Create a file in /etc/logrotate.d/ called 'logrotate_atmail_log'
2. In the file, put:
   

   /usr/local/atmail/webmail/log/*log {
       weekly
       rotate 5
       missingok
       notifempty
       sharedscripts
       postrotate
   /etc/init.d/atmailserver restart >/dev/null 2>&1 || true
       endscript
   }

3. Start logrotate:
   

   /usr/sbin/logrotate /etc/logrotate.conf

4. This will then manually execute the log rotation process.

The above logrotate options cause the following:

weekly

Log files are rotated if the current weekday is less then the weekday of the last rotation or if more then a week has passed since the last rotation.

rotate 5

Remove log file after 5 rotations.

missingok

Don't error if there is a missing log file.

notifempty

If there is nothing in the log file, don't rotate.

sharedscripts

Run the following script once, instead of once for each log file.

postrotate

Run the following script after log files have been rotated.

/etc/init.d/atmailserver restart >/dev/null 2>&1 || true

Restart atmail services.

endscript

Closes off the postrotate option.

 

There are many more configuration options that may suit your installation.
This may include adding an entry for other log files (eg the atmail/mailserver/spool/log files as necessary).
