Considering how long we've been slowly evolving toward RFC 2821 (which isn't
"done" yet), I wonder how long it will take to go beyond RFC 2821 to an RFC
with MUSTs around the helo data and reaction to bad helo data. Once there
IS such an RFC, finalized, than the world can slowly evolve toward that.

2030?
