This message you read now has an envelope sender: <[EMAIL PROTECTED]> while the From header is: mouss <[EMAIL PROTECTED]>. - if the message couldn't be delivered to you, an error would have been sent to the envelope sender. - An MTA can put the envelope sender in a header (Return-Path, ... etc) but this is not mandatory. - When you compose a message in your MUA, your MUA generally uses your From: address to determine the envelope sender. http://www.cns.utoronto.ca/usg/technotes/smtp-intro.html http://en.wikipedia.org/wiki/E-mail http://en.wikipedia.org/wiki/E-mail#Header http://en.wikipedia.org/wiki/Envelope_sender
