Exim on cPanel Behaving Strangely

Is your Exim not working properly with sendmail where PHP mail is functioning? Resolve the issue following instructions.

We have had an issue where Exim was not working properly with sendmail however PHP mail was functioning. We were unable to resolve the issue and cPanel were contacted. This was the resolution:

Set Exim to default

You can do this in WHM Home >> Service Configuration >> Exim Configuration Manager under Backup and Reset.

Documentation for this feature is available here:

https://documentation.cpanel.net/display/ALD/Exim+Configuration+Manager


After that was done, exim was checked to ensure that all of the files related to exim were correct and complete. To check Exim and other RPMs run:

/scripts/check_cpanel_rpms --fix
