Hello,
from my experience with SpamAssassin it is certainly true, that the
contents-checks get tricked.
I found that RTBL-queries help a bit and using Bayes-filtering with enough
feedback helps _much_. Bayes needs to be switched on. Then a big chunk of
ham/spam is needed to train it. Spamassassin uses messages with very large or
low scores to train automatically. It helps to train by hand for messages which
are spam, but not "spam enough" to be regarded as such by Spamassassin itself
(or which are considered as spam but not spam enough to be used for training
the Bayes filter)
