The ABNF in -protocol 3.4.1 is (mostly from a post by Wayne)

name = alpha *( alpha / digit / "-" / "_" / "." )
Will there also be a helo scope?
We can't use either pra or mailfrom because they break forwarding.
A HELO scope would be useful. I could publish records for that, whereas
I could not publish records for either pra or mailfrom for much the same
reasons as Tony has already described.
