Increasing anti-spoofing rules

[Anne Martin]

What options are available on the C370's for implementing anti-spoofing controls in order to protect our company from the increasing number of phishing emails using spoofed addresses?  

We already have an inbound rule to check the mailfrom: field and reject all messages that contain our domains

Hello Anne,

I hope that this tech-note may help:

This is a technote to assist with tagging possibly spoofed emails.

You can change the action to another action if you want it to be dropped or actions in some other manner.

Regards,

Matthew
