First pass:
sending domain publishes an authentication policy of some kind,
and the message passed the authentication tests
Why is a policy being required? Not all methods have policies, and some
methods can be used without a published policy.
The policy may not be explicit. For example, a DKIM-signed message which fails
will generate a policy query, and DKIM specifies a default to assert if none is
found. That's what I meant by "of some kind".
Instead say something like
The message passed the authentication tests. (This may require
accessing an authentication policy of some kind published by the
sending domain.)
Works for me.
The same comments go for fail:

Works for me.
The other value definitions are different, but need to recognize that
not all authentication methods require policies. I'd suggest this rewording:
softfail
The authentication method requires a policy to be accessed, but
the policy does not require authentication of all messages from
that domain, and the message failed the authentication tests
How about:
The authentication method has either an explicit (i.e. published
by the sending domain) or implicit policy, but the policy being
used doesn't require successful authentication of all messages
from that domain, and the message failed the authentication tests.
neutral
The authentication method requires a policy to be accessed, but
the sending domain does not publish any sender authentication
policy.
What if the method doesn't require a policy be accessed?
Actually in light of that question, maybe we don't need "neutral" at all. For
methods that have a policy, the verification attempt will produce one of the
other results. For those that don't have some queryable policy, "neutral" never
happens.
temperror

permerror

Works for me.
