As this thread has drifted off topic any way, would it for instance be a good idea to simply not accept mail from hosts that clearly use autoconfig ie reject all smtp from EUI-64 addresses. Of course not a wise idea for your own outbound relays which should handle mail from your customers but on the incoming side it might as well save a lot of headache and there is no need to keep track of which /64 are access networks.
That would be really, really bad. My 3750's won't accept arbitrary /128's in an ACL unless it's EUI-64 or I make up something similar that it will like. I'm sure I'm not the only person who owns a 3750. As such, my mail servers are using EUI-64 addresses. ~Seth
