Use postmap -q to test your tables.
Remember that a message may be base64 encoded or have
a phrase split between lines preventing body_checks
from matching. Inspect the message using vi, not a
mail program.
If something you think should be blocked by a rule
isn't, the reason is that a previous rule gave an OK
response.
