François Marier: Filtering your own spam using SpamAssassin
I know that people rave about GMail's spam filtering, but it didn't work for me: I was seeing too many false positives. I personally prefer to see some false negatives (i.e. letting some spam through), but to reduce false positives as much as possible (and ideally have a way to tune this).
Here's the local SpamAssassin setup I have put together over many years. In addition to the parts I describe here, I also turn off greylisting on my email provider (KolabNow) because I don't want to have to wait for up to 10 minutes for a "2FA" email to go through.
This setup assumes that you download all of your emails to your local machine. I use fetchmail for this, though similar tools should work too.
