you must not expect that a single mail changes bayes that much
if it would work that way you would risk with every single
training message to increase false positives or with every
single ham.training trash your spam detection

if it does your bayes is not really trained well with both spam
as well as ham - after enough training it reacts only in that
way if the message has a unique footprint and no neutralized
elements (neutralized = exists in spam as well as ham)

please consider to read how bayes works at all
