Enable or Disable Sender Filtering

Applies to: Exchange Server 2010 SP3, Exchange Server 2010 SP2

The Sender Filter agent is an anti-spam filter that is enabled on computers that have the Microsoft Exchange Server 2010 Edge Transport server role installed. The Sender Filter agent relies on the MAIL FROM: SMTP header to determine what action, if any, to take on an inbound e-mail message.

When sender filtering functionality is enabled on a computer, sender filtering functionality filters all messages that come through all Receive connectors on that computer.
