Huh. I was aware of 1891, but that's not our problem since it only
pertains to mail transports, not mail readers. I hadn't noticed 2298.

Still, the point about pointing out to the user that the return receipt
request isn't reliable still holds.

Right, just wanted to make sure anyone planning to write a patch was
going to write this part too. :-)

(The hanging problem is fixed in the snapshots which will go out in an
hour or so.)

Anyway, 2298 says:

   At most one MDN may be issued on behalf of each particular recipient
   by their user agent.  That is, once an MDN has been issued on behalf
   of a recipient, no further MDNs may be issued on behalf of that
   recipient, even if another disposition is performed on the message.

which uselessly assumes that every user has exactly one MUA. :-/ But
anyway, the intent still seems to be "send only one MDN". And I think it
would get annoying fast if you got another MDN every time I looked at a
message you sent me.

"Duh" :-)
