See #3.2 in RFC821 and then the careful commentary about it in #3.4 of
RFC2821.... ie: you consider the use of 251 or 551

You will probably very promptly conclude it's a waste of time because
no-one ever takes any notice of it, but YMMV.

You should start by becoming emperor of the world, after that it
shouldn't take more than a few decades
