Most mail servers when they receive mail don't want just a From: username Instead, they convert username to username@FQDN. Where they get that FQDN from is up to the mail server. It would seem really intelligent to use the value from the HELO or EHLO. But what if they used "valinux.co.jp"? Then your mail server appended that in, doing some of the dirty work for the spammers of making it hard to track down who really sent it. What it boils down to is the only thing you can _really_ trust is the IP address of the machine that hit your mail server. - -- Blue skies...
