you need to learn more about SMTP. SMTP doesn't care about mail headers. SMTP uses envelope addresses. when you tell you mailer to send mail to To/CC/Bcc, your mailer converts these into envelope addresse (used in RCPT TO commands). email headers are not for mail routing. From:, To:, Cc: ... are simply information to the recipient. and they can easily be forged. try this: $ telnet localhost 25 EHLO joe.example.com MAIL FROM:<f...@example.net> RCPT TO:<j...@example.org> DATA From: Uranus <nob...@foo.example> To: Moon <no...@bar.example> Subject: domedo blah blah . QUIT
