amavisd-new inserts envelope sender address into mail header since amavisd-new-20030616 (i.e. June 2003). Initially it was inserted as X-Envelope-From, nowadays the Return-Path header field is used for the purpose. To make it explicit to SA, the following lines are recommended in local.cf: always_trust_envelope_sender 1 envelope_sender_header Return-Path (although with some luck SA may guess correctly by itself) The change from X-Envelope-From into Return-Path came with a amavisd-new-2.0 (=20040701) release (actually already in a pre-release amavisd-new-20040301). The last version of amavisd that didn't insert envelope sender information into a mail header in any form was 20030314-p2. Mark
