HI Team,


We were testing the Proxmox anti-spam mail gateway and we have received lots of emails with DISPLAY Name spoofing.

Can any one help me with creating a rule/Regular Expression to prevent DISPLAY NAME spoofing attacks for our domain.
 
I think that you can increase spam score for HEADER_FROM_DIFFERENT_DOMAINS to higher for such cases.
