A good technique is to run a geospatially-enabled DNS server that maps AS numbers to locations and then simply serve different different results to different locations. AS number to geospatial mapping isn’t perfect, but it’s good enough. For example, when hosts in hinet location query your MX record, you could serve them the answer of 127.0.0.1 ;-) Spammers will love you! -mike
