May I ask to add Return-Path: some meaningful header line to sieve sent mail headers in vacation message? Now the header line isn't generated at all and the effect is as follows:
on receiving MTA: 2014-05-09T15:04:32+02:00 host/ip postfix/qmgr[2408]: 41F2F6024E: from=<>, size=900, nrcpt=1 (queue active) in received mail body: Return-Path: <> Would be nice to get: Return-Path: <user@domain> Copy of From: header line could be sufficient. Thanks. MU
