the problem of the OP is that he starts things the other side round and first reject without good evidence and don't have anything to make the system bullet profe because it's rejected
I remembered that I read a book about Postfix with the topic "Training with SpamAssassin". And the author was against additional training. The more you train the worst the result. With the motto "I cook an egg for more than 15 minutes, but it is still hard." They re other arguments for not autolearning, but my english is not that good to translate a complete chapter. And if there are some mails breaking through the wall, than it is better to create rules against the header. Clear facts without side effects. He also wrote that Amavis/SpamAssassin is learning itself. Each mail classified as spam with a score of more than 12.0 is learned as spam and there should be a logfile entry with loglevel 2 if a mail has been learned as spam. I never increased the loglevel to check that. I followed his opinion because it is the best book I ve got (www.postfix.de, next SpamAssassin/Amavis training course in November, I m thinking of participation)
