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.
