Email peering *IS* a smarter hammer. If all the cluefull email administrators would set up peering agreements with each other and exchange contact information, there would be fewer of these situations.
There's a lot more people doing SMTP than doing BGP. Also, AS1312 (us) and our related routing swamp does BGP peering with less than a dozen peers, but we end up talking SMTP to a good chunk of the world. I've got one machine that all by itself talked to 2,615 hosts in 1,612 second-level domains yesterday. Unless you're advocating a return to the X.400-style ADMD/PRMD stuff, this really is a non-starter. I don't have time to set up 1,600+ peering agreements, and possibly have to set up more just because somebody subscribes to a mailing list (either somebody elsewhere subscribes to ours, or one of my users subscribes elsewhere). And history has passed its own verdict on ADMD/PRMD.
