Well, I'm disappointed to learn that Gmail is also crappy. My understanding was that they did this part well, at least. To be fair, legit emails to misspelled addresses are not spam, per se -- just a consequence of being @gmail.com (with a humane name). FWIW, I run rspamd for half a dozen users. It correctly classifies upwards of 6000 spam messages, and ~300 non-spam messages per day. A dozen or so false positives get through per week, and I haven't seen a false negative in at least a year. I'm probably more annoyed by spam than most people are, but it has barely occupied any part of my brain in a decade. I guess my original comment should have been more specific. Spam detection is a solved problem in 2022, and has been for many years. That some providers implement it poorly is, well, crappy.
