Not to mention that nobody wants to receive a message that shows all 400 recipients in the To: portion.... :-) Or does alias processing only put the recipients in the RCPT TO: SMTP header and NOT in the To: RFC822 header... that would be ideal. Thinking about it a little more, this makes sense, so even if somebody did a "reply to all", it wouldn't get far unless the new sender also had the same alias defined. Let's say I define an alias AllMyFriends: f1@h1, f2@xxxxx and I send a note to AllMyFriends The SMTP headers will look like... ... RCPT TO: <f1@h1> RCPT TO: <f2@h2> ... DATA Subject: A message for all my friends To: AllMyFriends ... So the message delivered doesn't have the entire distribution list enclosed anywhere.. the SMTP headers are not sent to the end client.
