Oh, sorry. I completely misread your post. (I was thinking that weaponsboy at gci dot net didn't really fit you, Jamie...) The envelope from header is how the message gets routed with SMTP. The "FROM:" header is meaningless, and is actually part of the message data. You can test this by telnetting to your mail server and sending yourself a message: jfzuelow:~> telnet mail.juneau-lug.org 25 Trying 24.237.22.218... Connected to mail.juneau-lug.org. Escape character is '^]'. 220 nova ESMTP Postfix HELO IMASPAMMER 250 nova MAIL FROM: <imaspammer@xxxxxxxx> 250 Ok RCPT TO: <info@xxxxxxxxxxxxxx> 250 Ok DATA 354 End data with <CR><LF>.<CR><LF> TO: weaponsboy@xxxxxxx FROM: freds_gift_shop@xxxxxxxxxxx SUBJECT: Impress your friends! After a blank line the headers are done and you get the text of the message. And to finish it off, a dot by itself... . 250 Ok: queued as 14E7BF6 QUIT 221 Bye Connection closed by foreign host. So when you look at the headers of that message, you'll see a TO: line of "weaponsboy@xxxxxxx". But the mail server saw "info@xxxxxxxxxxxxxx" and acted accordingly. (And even now, imaspammer@xxxxxxxx is receiving the bounce from my mail server, as this message set off a couple of SpamAssassin rules...)
