Using Delivery Rules for a List-Server Mailing List

You can use delivery rules to reject incoming mail to a list-server mailing list based on the contents of To, From, Sender, Subject, the entire message Header (everything but the body of the message), or the Body of the message. See Setting Inbound Delivery Rules for IMail Lists.

Note: Delivery rules can also be applied to all mail for a mail host or to mail for individual users.
