If the value is greater than 150, the email is marked as spam, and deleted if the trigger file exists.

The smut table follows. It has the same auto-deliver and subtractions as above, but concentrates on the overly offensive sexual email. Care has been taken to only trigger on the worst "catch phrases" so that normal conversations between romantic people does not get censored.
