My Bayes don't score any spam

[forum]

I am a student and testing SA for my project. Thus, I change sub tokenize_line to produce an output that i want. Now my Bayes was learnt about 350 hams and 350 spams but it has only 650 tokens.   When I use spamassassin -t command to test my mail, Bayes was working properly. It give a spam score as i desire. When I try to send mails via outlook express, there are no score form Bayes.   Why it don't produce any score? Is it because I've go too low amout of token?   Sorry for my poor english Thanks
