Description of Problem:
Recipients claims to never receive mail from me when I send (I doubt their
veracity).

Steps to reproduce the problem:
1. Send mail.
2. Call next day to see if they received it.
3. They say "no."

Actual Results:
Mail goes out and no notification comes back.  No UI is provided (that I'm
aware of) to request delivery status notification.

Expected Results:
Should be able to request delivery status notification (DSN) for an
outgoing message.  Would be better to be able to make DSN a default.  Even
better would be to allow DSN specification for individual contacts (akin to
the "wants HTML mail" checkbox.  Even better would be to specify that for a
given category (e.g., "Business").


How often does this happen?
