so, what would you manually learn?
Mangling data by exchange is a big. problem when trying to filter
spam in front of it. I see two ways to avoid this problem:
- use spam server for exchange. We use one from GFI, with quite good
results.
- you can use spam filter in front of exchange, store copies on it and
learn from them. However, you will probably be the only one who can train
spamfilter in such case.
you actually _can_ train from messages that went through exchange, but
mangling by exchange will somehow blur the results and lower bayes
accuracy.
