For instance, I (semi-seriously, semi-facetiously) proposed "XM" records some years ago, whose value would be 0 or 1: hosts with 1 send SMTP traffic, hosts with 0 don't. Thus every MX's behavior could be to reject all port 25 SMTP connections from hosts with XM=0. There a lot of problems with this idea, and if memory serves, both Dave Crocker and John Levine pointed them out at the time. But I think that perhaps it's time to revisit the general concept and see if it could be made to work for (as Bill said) "legitimate behaviors in a generalized model". This would not only allow us to address SMTP abuse, but (for example) zombie hosting of DNS and HTTP servers. ---Rsk
