 Define lists of senders whose email will never be accepted for delivery

 If the Policy Sender Deny list denies a sender and the user adds the sender to their allow

list, the sender is DENIED. i.e. the Policy Deny list takes precedence over the User Allow list

 If you utilize one mail server, you can add your own domain name to your Deny List. This will

prohibit Domain Spoofing and Domain Harvest Attacks. (*@Mydomain.com)

Deny List options allow you to perform on of the following

 Deny Delivery – deny and bounce the message back to the sending MTA

 Accept and silently discard the message – accept the message from the sending MTA
