Server Wide Spam Email Blocking using Exim and PCRE

As a WHM Administrator, I would like to have a system in place to set lists of wildcard (and normal) email addresses to block from all accounts on the server so that spam-sending domains can be easily blocked from all server accounts rather than simply individual accounts. This would be a great help in reducing spam appearances in customer's mailboxes.

As a WHM Administrator, I would like to have a system in place to set lists of wildcard (and normal) email addresses to block from all accounts on the server.

This can be done currently with settings in the Exim program, but this is delicate and prone to error and issues.

A WHM interface (just like the SpamAssassin account-level interface) for setting domains and [incoming] email parts to be ignored by the server would be a great GREAT help.

Such as:

Ignore emails that:

*@horsesdongs.co.uk --- No incoming emails from this domain are delivered.

*@*edu.icu --- No incoming emails from any domain name ending in "edu.icu" are delivered.

massiveweenie --- No incoming emails containing this string in their from address are delivered.
