Since the kinds of people who typo squat probably don't care about 
setting up MTAs properly, and probably care less for standards; how do 
we prevent them abusing partitions, slow networks, and/or high pre-URS 
TTLs to "guide" emails to their servers that don't/won't respect a lower 
level MX record? Wouldn't it be easy enough for the typo squatters to 
"pre-cache" the MX / A records on major ISP's recursive servers at the 
time of registration with very high TTLs to circumvent this strategy?
