Well, I think you would need to parse for the URI/URL. Get a
raw IP value for it, and then use MD's relay_is_blacklisted
function, and use one of the RBL's that only returns geographic
codes. From that point, you would have to just match the return
value from relay_is_blacklisted against a known list of IP's
returned from the RBL as being "elsewhere".
