deleting mail based on bogus criteria is not keeping mail usable.  it's 
killing it.

Real life spam filters use metrics and tune to the actual behavior of 
mailers.  If most of the mail that comes from domains with AAAA and no 
MX is spam, they'll tune for that, and it won't be a mistake.

yes it will.  partially because the behavior of one domain is generally 
independent of that of another, partially because the volume of mail 
produced by such domains is largely independent of the behavior of any 
single domain, and partially because spammers (being a smaller 
population) will adapt more quickly to avoid getting trapped by this 
shortsighted hack.

For the forseeable future, most such mail will be from zombies, and it'll all
