The To: headers are not used by the mail server to send mail. The conversation between a client and a server goes something like this (S: = server responses, C: = client commands): # telnet localhost 25 S:< 220 net1.alma.ch ESMTP Postfix C:> HELO localhost S:< 250 net1.alma.ch C:> mail from: <sender@domain> S:< 250 Ok C:> rcpt to: <someone@somewhere> S:< 250 Ok C:> rcpt to: <[EMAIL PROTECTED]> S:< 250 Ok C:> data S:< 354 End data with <CR><LF>.<CR><LF> Now is when the client sends all headers, followed by an empty line and the body of the message. The To: and From: headers here (which will appear in the receiving mailer) can be anything, including completely bogus (often done by spammers). The server really send the mail to the recipients given in the "Rcpt to:" commands, and completely ignores the To: header which is just part of the Data stream. SMTP servers answer on port 25, so you can read the SMTP RFCs (822 and/or 2822) and play with your server through telnet if you are interested.
