How to Reject Fake/Spoofing Email?

[skyknight]

Hi,

Recently, my user got a lot of email from fake/spoofing email address like: "Someone I Know <[email protected]>" <[email protected]>

I want to reject all email that contain double @ in from header ($h_from: )

What regex can I use in exim filters (/usr/local/cpanel/etc/exim/sysfilter/options)?

Thank You
