It sends the bits in the envelope address. This information is received with - The MAIL FROM command in SMTP, - The Postfix sendmail command (with -the -f option, the default is the local UNIX user, and that is probably your problem), - Or with the rarely-used qmqpd service. > The HELO/EHLO stuff was clearly myself being miss lead by something I > read from some a google search!
