ISC uses sendmail.  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.
