Case (a) is not that common yet, and is easily picked up by content-filters.

Case (b) is a lot more difficult to deal with, I admit.  If your server
can correlate incoming NDN's with previously-sent outgoing mail, it's
possible to do something intelligent, but getting this correlation is
tricky, because different NTA's preserve different information from the
original message.
