Check the Mail log on Plesk Server
Wednesday, August 21st, 2013The Plesk mail logs are kept in /usr/local/psa/var/log/maillog
The best command to use for viewing the logs in real time is
tail -f /usr/local/psa/var/log/maillog
If you are not familiar with Linux commands such as vi, tail, cat etc you can see the manual for any command by typing man
Thank you.
