I had the same problem with postfix + maildrop, as local(8)=20 unconditionally adds the 'From ' header when delivering to an external=20 command and upstream did not consider my suggestion to make this=20 configurable. The work-arounds I came up with: 1. use 'reformail -f0' as suggested in maildrop(1) reformail(1): -f0 Any initial blank lines are removed. If the first non-blank line is a= =20 "From_" line, it gets converted to a "Return-Path:" header, and any existing "Return-Path:" header gets removed. If the message does not=20 start with a "From_" line, the message remains unchanged. 2. adjust the 'maildrop' destination in postfix' master.cf to remove the=20 'F' flag. pipe(8): F Prepend a "From sender time_stamp" envelope header to the=20 message content. This is expected by, for example, UUCP software. 3. Deliver from postfix to a Maildir, bypassing any filtering. Kind regards, Andrei --=20 If you can't explain it simply, you don't understand it well enough.
