PART 2. MAILBOX FILTERS

Mailbox filters, also called Sieve filters, filter messages containing specified strings found in the message headers and apply specified actions to these mail message. Administrators can filter mail streams going to a user, through a channel, or through an MTA. Messaging Server filters are stored on the server and evaluated by the server, hence, they are sometimes called server-side rules (SSR).
