Global email filter for all websites under WHM

[FUNKAM55]

I have several websites under one WHM and have to add global email filters to each cPanel individually
i often add the same filter many times to different website cpanels
is there any way for me to add it once using WHM
Please bear in mind I’m a total newbie to WHM
thanks

Hey there! This isn't a WHM tool for this at this time, but you might want to check out our documentation about customizing the Exim system filter:

How to Customize the Exim System Filter File | cPanel & WHM Documentation

The Exim system filter file scans messages that your server has received, but that it has not yet delivered. To add custom filter rules to your Exim configuration, you may either create custom filter rule files for Exim to include in its configuration, or create a custom Exim system filter file.

docs.cpanel.net

This would be applied globally to all accounts on the server since it is a root-level change to how Exim handles content.
