How to filter email using regex or other technique?

[ashur4x]

My email server is attacked by suspicious email and I want to filter it.

The email body has a familiar email name in the form of hyperlink. It also use a familiar email subject.

I'd like to filter this email. Perhaps, using a regex that detect a single word text and contain "@ash.com". It is even better if I can combine the filter as if it's a hyperlink. I'll attach some images about th email virus.

I'm new about filtering emails. So, any help is greatly appreciated

Hi,

You can make use of Exim filters as our documentation states here:

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.

We have a few examples of some use-case scenarios as well as with the steps to inplement them at our support articles:
