Description of the problem

The server is sending an email to you which is alerting to potential problems with the automatic upgrade of EXIM. This email means that your cPanel has automatically updated your exim installation, but was unable to complete the upgrade as it believes you have some custom ACLs (Access control lists) in the exim configuration that it is scared of overwriting.

Example

The whole text of the email you would receive is below:

cPanel was unable to automatically merge your Exim configuration with the new settings that 
shipped with the build you have installed (11.25.0-RELEASE_42404) because you have a custom 
ACL configuration which cannot be automatically configured.

To avoid any mail downtime, we thought it was best to leave your previous configuration intact 
until the new configuration can be properly installed.  In order to complete this configuration 
update, you will need to manually merge your configuration with the new configuration settings.  
Please follow the steps below to complete this update:
        1. Enter the Advanced Configuration Editor
        2. Notate any custom changes you have made in the ACL section.
                        You may also which to make a copy of /etc/exim.conf.local
                        and /etc/exim.conf.localopts as custom settings are contained in these files.

        3. Click the 'Reset ACL Config to Defaults' button.
        4. Reinstall your advanced custom settings.

Note: Until you manually complete this update, automatic spam filtering may have been rendered 
inoperable to prevent any mail loss.  (This generally only applied is you were upgrading from cPanel 10.x)

Solution

If you have not made any custom ACLs (this is likely to be the case, if you dont know what this email means), then you can stop this notification and complete the upgrade when you log in into your WHM control panel (with https and port 2087 e.g. https://yourserver:2087) then in the menu on the left click on 'Exim Configuration' then at the bottom of this page you can click 'Reset ACL Config to Defaults', once done the upgrade will be completed.
