Sendmail does support the return receipt, however, most user level mail programs that make and send your message do not. The Return-Receipt-To: header must be inserted prior to the Subject: line in order for it to work. While the experienced, Internet connected user can do "telnet ism.isc.com 25", and construct the entire message by hand, this is beyond most users. I do not expect that mail, mailx, or things like elm will put this header in for you, though I could be corrected. Our Ten Plus user level mail software does permit this, so I would assume that there are other packages out there that may permit it as an option. P.S. The return receipt comes back to the user as mail from MAILER-DAEMON, and therefore would probably be confused with a mail bounce unless you noticed the subtle "returned mail: return receipt" on the subject line buried in all those mail headers :-) However, this may be useful for the curious.
