Enough people have asked that I'll explain why envelopes are seperated from headers in mail. Lets say I'm sending mail with the following header To: foo, bar, baz Mail gets stored and forwarded many times during its delivery process on a large internet. If at every stage the only hint the mailer had for delivery was the header address, every mailer along the way would have to generate three copies of the mail in order to guarantee delivery. Kind of nutty, eh? Thats why there is a seperate envelope. When you generate the mail, three seperate copies will be produced with seperate envelopes indicating the mail whould be sent to "foo", "bar", and "baz", and the mailers in between don't look at the headers at all. This is a slight simplification because envelopes can contain multiple addresses -- but thats when you are sending one message to many people via a common path -- the mailer at the last step where the mail can take a common path is expected to break the envelope up before sending it further along.
