So have I, but that doesn't change the fact that Yahoo's official position is that such messages are not real.  I think that their response was incorrect, but interestingly, when other people have asked, they get the same answer (when they get any answer).  Furthermore, NNFMP is not registered in the IANA's list of valid protocols, so if it were real, Yahoo would [or should] have registered it.  Since I reject messages that they told me were forged, if that's not true, it's their problem for misinforming us.

You should find it curious (like I did) that when the question was asked on "answers.yahoo.com", Yahoo deleted the question and answer.  If NNFMP were legitimate, then why would they delete questions regarding it?
