Hmm... If you are training Bayes, and all of your ham is in English, then what does Bayes do with the Chinese ham your customers get? > Real SPAM is really SPAM. For everybody.

It's the vast differences in ham that I am more worried about. Our customers are salesmen for the most part, so they are constantly sending and receiving marketing type emails. For us, marketing stuff is almost always considered spam. I think this would cause a problem with false positives for our customers if I train Bayes based on our idea of ham and spam. > If you are sane and try to not make mistakes with bayes, it works > phantastic.
