I do everything on a scoring basis,  so this would just be another score
in the pile.    Perhaps another function, maybe called ScanMX would look
at the domains list of MX servers and nullify or negative score a
connection with MX servers listed in the same ip subnets.

Mail from billybob at  from ip no listening smtp
server +3.00


ScanMX result -3.00



ScanMX result +3.00

This would also help eliminate those pesky mailservers that bypass MX
lookups and go straight to the domain ip.   Usually virus or spam.
