Sounds like you need the qmail mfcheck patch. You might already have it -- try "echo 1 > /var/qmail/control/mfcheck" and restarting qmail-smtpd. Then try relaying to a local user from an untrusted host (not a RELAYCLIENT in your tcp.smtp), You should get a "553 sorry, your envelope sender domain must exist (#5.7.1)" when using a BS envelope sender . Not all MTA's give you the pretty "Return-Path" header like qmail does -- SA was made to work with those too =] -- Tim Wesemann Voicenet Systems Administration
