Not true (in practice). User chooses "Delivery Receipt" in their MUA's
options, and the MUA ensures the Email message is submitted to it's MTA with
DSN enabled. Under sendmail that is done via the MUA calling 
"sendmail -N failure,success", under SMTP mailers it's done by the SMTP
client itself.

All this talk about "Disposition-Notification-To:" is interesting - it looks
like an extension of "Return-Receipt-To:" - i.e. the delivery receipt
solution in pre-DSN days! [So it wasn't so bad after all! ;-)]
