One user on the german mailing list observered that any SMTP delivery (even to 127.0.0.1 and to a content_filter in his case) causes mailaddresses to be rewritten according to smtp_generic_maps
Alas, the docs say: smtp_generic_maps: Address mapping lookup table for envelope and header sender and recipient addresses while delivering mail via SMTP. Correct. "ADDRESS_REWRITING_README" on the other hand says: "... when mail leaves the machine via SMTP" (emphasis on "leave") and in "STANDARD_CONFIGURATION_README" we see: "This mapping happens ONLY when mail leaves the machine" (emphasis on "leave") One might argue that a delivery to "127.0.0.1" and/or "localhost" does not really make the mail "leave" the machine. That particular user now uses an lmtp transport to feed his content_filter and all is well, but either the docs could be made to match the behaviour (or the other way round). -- Ralf Hildebrandt ([EMAIL PROTECTED]) [EMAIL PROTECTED] Postfix - Einrichtung, Betrieb und Wartung Tel. +49 (0)30-450 570-155 http://www.arschkrebs.de I'm looking for a job It's not that I'm so smart , it's just that I stay with problems longer. -- Albert Einstein
