If I understand correctly, the BAYES_X tags add a value corresponding to the X value. So BAYES_99 is basically adding 0.99 to the spam score?
Ideally I feel it should be possible to scale this value such as by using simple multiplication or even exponentially. Is it possible to increase the score associated with the BAYES_99 and BAYES_999 tags? PS: Is it possible to see what values are associated with all tags for debugging purposes? Meaning can I run a command that dumps a list of all tags and their associated values so that I can decide which tags could have their scores adjusted? PS2: Is there a tag that indicates that the message contains a large amount of non-latin1 text? I do get a lot of legitimate non-ISO-8859-1 messages but usually it's just a name or at most an address. So less than 100 bytes.
