Can Policy Patrol block mail relaying?

 

Yes Policy Patrol can stop spammers relaying messages via your mail server (if you enable Recipient verification). By enabling Recipient verification Policy Patrol will reject any externally received emails that are not addressed to a valid internal email address. This means that Policy Patrol blocks address harvesting, but also mail relaying since no externally received messages can be sent to external recipients.
