I believe that what the technical measures AOL and MSN are doing today are just stopgap measures that reduce the spam volume temporarily, but have only sent the spammer scrambling to set their networks up with reverse DNS and acceptable rDNS names. The only measure that is somewhat effective is the flock of lawyers you can point to the senders. This will only encourage another level of technological indirection to distance the spammer from the sending networks as they scurry to hide from the flock of lawyers. Spammers can set up their networks to comply with the newly proposed DNS based SMTP authentication techniques as easily as I can. The next generation of RBL will need to block based on the authoritative DNS IP to get around this "DNS controlled by spammer". As has been pointed out elsewhere, SMTP Greylisting can easily be bypassed with today's spam tools. I predict that 6 months from now, AOL will see the same overloading crisis on their mailservers that led to the drastic measures in the last month or so.
