I also get bitten by this problem (on Cyrus 2.1.3.) What is the rationale for Cyrus deliver to put in this header? I could imagine that once a mail gets through Sieve (via LMTP which perhaps may be interpreted as equivalent to SMTP for the purposes of RFC 2821) bounced mail (to Return-path) should go to the Cyrus administrator!? If this is the reason, it would be nice if Cyrus could be configured to let the MTA handle the Return-path. Thanks in advance for any comment. -Hein
