Spam filters rely on many signals besides the from address to decide if a message is spam, because one signal alone is often not reliable enough.
It’s hard to see who deals with spam with the best because when the filters are working well, you don’t notice how much is being blocked.
I can say that both Fastmail and Google work fairly well. Unless things have changed, about 90% of email is spam, with most getting blocked or diverted at different levels. So even if some gets through, it’s possible the systems to block it are still working very well.
