Tony,

TF> We can't use either pra or mailfrom because they break forwarding.
Taking andrew's proposal as an effort to process SPF "classic"
through the IETF, I suggest not trying to expand the scope or
redirect it.
The issue of forwarding for author-based path registration schemes,
like SPF and Sender-ID, has been discussed at length. At a minimum,
we need to document these impacts on usage.
However there is already a deployed base of some size, for SPF, so
we know that there are usage scenarios that the community find
helpful.
I suggest we make sure we document all this, rather than
re-targeting the technical focus.
