Why am I making an issue over this?
Other programs put the receipt request at the end of the headers.  When the
receipt request is put near the beginning (as is the case in Mozilla) some
servers treat it as a DSN receipt request instead of a MDN, and some e-mail
programs don't return a receipt at all because the request is not in the
standard location.   My suggestion is to move the header for MDN return receipts
to the end of the headers, like in OE 6.

Marking as new, reassigning bug, and changing component from
compose to backend.

adding myself as qa, adding seth.

Also we had Disposition notification header in same place (top)
in current 4.x builds.

Comment 3

[Jeff Tsai]

It doesn't really matter where is the Disposition-Notification-To: placed as
long as it is withing the message headers segment. Servers should not treated
the DNT header as DSN request. If they do they are not standard compliant. Even
if they do no matter where it was placed the behavior should be the same. In any
case, DSN request were made through out of band channel, a server should not
treat DNT header as DSN request. That's wrong, wrong, wrong. And we shouldn't
fix anything which is wrong from the begining.
