Something to consider is that it was *also* created by Paypal & banks, which 
are frequently spoofed/phished.  Not to mention Linkedin & Facebook...

This is an effort to help reduce spoofing, and incorporates DKIM & SPF into a 
policy spec.

What it means is that a site can say people reject any mail that doesn’t match 
our specs, but it also allows for reporting of just how much spoofing is 
happening.

 - One element of the policy is to send reports of errors back to the domain 
owner, which can be invaluable in seeing what others are doing in your name.

Thing about it this way: If you’re on gmail or another site that honors DMARC 
records, it’s pretty much eliminated spoofing & Phishing emails from paypal & 
banks.

As for Yahoo or AOL:  It could be considered a method to push users to use the 
web interfaces more, or just send through the companies servers.  Most do 
already, to be honest.
