True. But the world must progress too. It would be nice if the spam-issue is better solved on IPv6 (than on IPv4). You 
would then have a reason to /not/ accept on IPv4 (and  give IPv6 a boost). 

There must be a good reason for people to get of their asses and start implementing things like DMARC. All the banks 
(!$%^) I talk to do not have any reason to implement it swiftly (they turn on p=none and then all progress stops). 
Frustrating that they are too lazy to implement a few DNS records. 

It only needs firm backing by 3+ large companies like Hotmail. Give everyone on IPv6 without DMARC a large spamscore 
(and publish that beforehand ;-) ). Give me ammunition and all corporates will move.

Most are not authenticated. The vast majority of SPAM I see is, among other things, Joe Jobbed.
