======SMTP Rules======
Download rules are applied to messages which arrive at VPOP3 using SMTP - either locally sent messages, or incoming messages received through an SMTP mail feed.

To configure the rules, go to the VPOP3 settings, then **Services -> SMTP Service -> Filtering**. There is an **Edit SMTP Rules** button which brings up the SMTP rule editor.
