It seems that draft looks rather confusing. Let me try and restate the
catch:
Client: I'd like to say Verified Hello and be whitelisted.
Server: Nope, I need to verify XYZ in order to whitelist you.
Client: OK, I've logged that. I'll just send by regular Hello then...
(Alternatively, client can send via BigESP, if being whitelisted is a
requisite for this message.)
Postmasters may count the occurrences of the XYZ keyword before
deciding what vouching enhancements it is worth to go for. I noted
that, while Microsoft has other means to push for, say, Sender-ID,
VHLO would enable even less massive ESPs to etch receivers' logs with
the name of their favorite filtering policy.
He said:
Ah, a branding exercise. That hadn't occurred to me. Who knows, it might
work. Point it out on the ASRG list, we'll see if there's any interest.
Anyone?
