You can barely browse the web at the moment without stumbling across
some college grade programmer who's implemented a version of it.
That sort of approach is OK if you are either:
a) Only filtering e-mail for one recipient, or
b) Filtering mail for lots of recipients, but they all receive
very similar e-mail
If you have lots of recipient who get different sorts of messages (say,
you're doing this at a bank, and a bunch of your users get financial
information by e-mail, and a bunch don't) a simple Baysian implementation
doesn't work.
Even if (a) and (b) do hold, the rules typically need to be trained on
a per-user basis with a spam/non-spam corpus as necessary. That's
probably feasible at small organisations, but it's not practical at
larger ones.
