What am I missing?
It says that you should look at email without a signature as being
"acceptable", unlike a "I sign all mail" which without a signature
is quite questionable.
From what I can tell, "I sign some mail" tells the receiver that the
signer wants to put up a policy statement, but that's about it. The
one thing that's vaguely interesting about this is that we could do
surveys of who's at least thinking about dkim.
The "I sign some mail" (an open-ended list) also indicates that when
a signature is damaged by a mail-list for example, this source should
be considered valid for their OA. An open-ended list also allows
positive annotations, but with fewer delivery failures or support calls.
I have no idea what an "OA" or "open ended list" is, but I seriously
doubt it. Preferential treatment
based on unverifyable DKIM-Signature bits is an invitation for abuse.
