OK, as a receiver, can I blame the sender for any problems with
legitimate email being rejected due to DKIM failures? If a receiver
can't transfer the blame to the sender, why should the receiver treat
this any different than just being suspicious?
I think some site like a Bank, that is heavily phished, might go so far as
"I sign all mail. Please delete/reject/drop/whatever (perhaps even
all messages that fail to verify".
That site would have to be pretty confident that the genuine mail it sent
out was 100% clean, but it might well decide that it was a lesser risk to
have some genuine messages dropped than to let phishes go through.
BTW, are there any plams to have keywords for some of the various policies
that might be declared, so that verifiers (or rather their policy modules)
could recognize them and adjust their policy accordingly)?
