Postfix cashes to test result for a configurable time spam, with
separately definable ranges for positive and negative test results.
It is - after an initial learning period - basically a hash table lookup
without the hazzles of manually generating the lookup table.

Still no problem, as postfix has to deliver the mail sto cyrus somehow,
either smtp or lmtp. The verification simply works here.
