The best way to help end-users avoid getting phished it to not accept
phishing messages for delivery.  DKIM-SSP where strict policy
statements are published offer a mechanism for this.

I get a message from security(_at_)ebay-verify(_dot_)com(_dot_)  It has a 
valid
signature.  I check the SSP for ebay-verify.com, which says "MAJOR
PHISHING TARGET, ACCEPT ONLY WITH SIGNATURE."  So I drop it into the
recipient's mailbox with a gold star on it.

What have we just accomplished?

Nothing and it would be DANGEROUS to do so.

But read the subject title:

        SSP = FAILURE DETECTION

If ebay-verify.com's SSP has exposed an inconsistency in the signature, then
it can eliminate the JUNK with no HARM done and with 0% FALSE POSITIVES.
