PMDF System Manager's Guide

The receivedfor keyword instructs PMDF that if a message is addressed to just one envelope recipient, to include that envelope To: address in the Received: header it constructs. receivedfor is the default. The noreceivedfor keyword instructs PMDF to construct Received: headers without including any envelope addressee information.

The receivedfrom keyword instructs PMDF to include the original envelope From: address when constructing a Received: header for an incoming message if PMDF has changed the envelope From: address due to, for instance, certain sorts of mailing list expansions. receivedfrom is the default. The noreceivedfrom keyword instructs PMDF to construct Received: headers without including the original envelope From: address.
