I created a sample message, then tell spamassassin to learn it as spam

wrong? Please help!
Training a message as spam does not guarantee the next time the exact same
message is seen that it will be scored as spam. It's not a "poison pill"
tool.
Training a message as spam tells SA that messages that look similar to the
trained messages will be scored "more spammy" than they otherwise would
be. This may push the overall score past a threshold.
Three things you need to look at:
(1) Have you trained enough spam _and_ ham messages to give the bayes
database enough to work with to make decisions? Run "sa-learn --dump
magic" and verify that you have at least 200 spam _and_ 200 ham tokens.
(2) What was the bayes score on the message the first time you passed it
through SA for scoring, _before_ using it for training?
(3) What was the bayes score on the message when you passed it through SA
for scoring _after_ training?
