[mailconfigupdate] Unable To Automatically Update The Mailer Config On SERVER

I've added this:

# Added for me
hostlist privaterelay_hosts = lsearch;/etc/privaterelay

And changed this:

accept hosts = +relay_hosts

Into this:

accept hosts = +relay_hosts +privaterelay_hosts

within the Exim Advanced configuration editor. Cause I wish to allow a relay without authentification.

This morning, I've got this:

cPanel was unable to automatically merge your Exim configuration with the new settings that shipped with the build you have installed (11.23.6-RELEASE_27698) 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.

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)

Current Config Version: unknown
New Config Version: 4.900000

What can I do to prevent this ? Cause last time, all mail was receiving a 550 (SMTP Protocol Returned a Permanent Error 550 Sender verify failed) which is pretty bad...
