[IMail Forum] probability

[Adam Campbell]

Can someone give me a quick lesson on how to adjust the good/spam 
numbers in the probability test?  I know HOW to adjust the numbers, but 
I'm fuzzy on what to adjust them to.  I've been using a ratio of 1:2 for 
okay words and upwards to 1:9 for undesired words.

The following is from a personal (non-business) message and is happening 
a little too often:

SMTP (262c01b40220641c) The following words were used to compute the 
probability email is spam
