apparently.

There's a bunch of [DISCUSS] saying that this should
be PS and DNSOPS instead of "research", because it's
no research.  I don't see that the IETF in 2008 did
not like this peculiar 127.0.0.2/8 usage.

I'm talking about the "MAILFROM identity" in your
draft.  Of course that is based on SMTP MAIL FROM,
821/2821/5321/5321bis.  But as an "identity" for
reputation it is defined in 4408/4408bis.

The SMTP RFCs are not about identities, they don't
tell you what to do with an "empty" MAIL FROM if
you want to attach some kind of reputation to it.
RFC 4408 explains this trick.

If some scheme has no use for empty MAIL FROMs it
is fine; otherwise it should follow the definition
in RFC 4408.  Or use another name, "MAILFROM" and
"PRA" are already taken.
