Has SpamAssassin seen both 200 hams and 200 spams ?  If not, then
SA is still in training mode and won't score emails until you have.

https://cwiki.apache.org/confluence/display/SPAMASSASSIN/BayesNotWorking
has some things to look into and try (bayes_min_ham_num and
bayes_min_spam_num can be significantly lowered in local.cf, IME).

Note, some SA rules which override normal scoring, such as
whitelist/blacklists, will prevent it from learning from an email.
