Authentication says the mail is really from you.
Yes, although SPF doesn't authenticate anything. It says whether a
given IP address is *authorized* to send email claiming to be from a
given domain. This is a pretty black or white determination.
Accreditation says you're worth getting mail from.
Accreditation and reputation are both going to be value judgements
that are much less likely to be used as a black or white
detemination. This makes accredidation something very different than
what SPF is currently designed for.
