You must understand the difference between the "envelope" and the "headers". The MAIL FROM command specifies the _envelope_ sender. The fact that this gets written into the Return-Path header is a good thing, but it happens at delivery time (and it is optional. see the manpage of "pipe"...). to play with the sender address, use smtp generic maps. but better set the correct sender address at the time the message is sent. users can do "sendmail -f $sender...". This is better than relying on headers. and it follows an old principle: fix problems near the source.
