I love the "Filter Incoming Emails by Domain" feature - as we can eliminate known spammers from contacting all the users in our server.

Obviously I don't want to block the domain @gmail - but is there a way to block specific email addresses from within WHM ? I know I can do this on a per-account basis, but I want to do it on a global level.

Thank you.
