cPanel : "The Exim database is most likely corrupted and the following steps should be followed"

If you are seeing the following error in the exim logs, you will need to reset the exim databases.

“The Exim database is most likely corrupted and the following steps should be followed”

To reset exim’s database of retry, reject, and wait-report_smtp attempts on cPanel, I find the safest way is to run the following commands.

/usr/sbin/exim_tidydb -t 1d /var/spool/exim retry > /dev/null /usr/sbin/exim_tidydb -t 1d /var/spool/exim reject > /dev/null /usr/sbin/exim_tidydb -t 1d /var/spool/exim wait-remote_smtp > /dev/null service exim restart

You can change the duration of the cleanup (from 1d to 2d etc).

This issue usually affects emails from domains like gmail, hotmail, aol etc.
