Note, from section 2.1:
While Internet standards normally do not specify the behavior of
user interfaces, it is strongly recommended that the user agent
obtain the user's consent before sending an MDN. This consent
could be obtained for each message through some sort of prompt or
dialog box, or globally through the user's setting of a preference.
The user might also indicate globally that MDNs are never to be
sent or that a "denied" MDN is always sent in response to a request
for an MDN.
Also, unlike web bugs, this mechanism does not allow a doubleclick-ish
tracking system to connect an actual email address with a previously
anonymous browser cookie.
In any case, this particular memo is from 1998; maybe I'm not looking
hard enough, but from where I sit, it isn't exactly setting the world
on fire.
