> Having to check a spam filter defies the purpose of using one in the first place.

I disagree with that; I consider the user-experience of having a spam folder that you check occasionally — but less frequently than your main inbox — to be better than that of having no spam filter at all, and also better than that of blindly trusting the filtering software (or whatever kind of filtering-system that the server operator uses… especially the comment-filtering systems in non-email, publically-visible discussion systems run by huge for-profit companies such as Twitter, YouTube, Reddit, etc., i.e. the kind "that employ a large body of low-wage overseas labor" to manually or semi-manually filter stuff that tau mentioned above) to not produce any false-positives.

(Revisiting what I said earlier about client-side email filtering: if you run SpamAssassin on the client-side, you can take any false-positive messages that end up in your spam folder and pass them to the sa-learn utility as "ham" messages, and also take any false-negative messages that end up in your main inbox and pass them to the sa-learn utility as "spam" messages, in order to train its filtering model to produce fewer incorrect results in the future.)
