If I add a teaspoon of red wine to a 50 gallon barrel of clear water, 
should the resulting liquid be red?

Depends on the contents of your bayes DB.. if that particular spam mail had 
mostly well-recognized HAM tokens with very strong ham scores, a single 
message isn't going to change much.

However, if the spam has mostly unrecognized tokens that didn't exist 
before, a single message training is going to make a dramatic difference.

Remember, bayes is all about statistics and spam probabilities of the words 
and headers that make up a message, it's not about message itself.

You can run the message through spamassassin -tD and see what the bayes 
tokens in it are, and what their probabilities are.
