On the other hand, as much as I dislike Google, I use Google to filter spam on my email on my own domain and it seems to be extremely effective at that particular job. Over past 6 or 7 years I have been using Google I remember only one case when valid mail was classified as spam. I receive about 10-20 spam a day and I get about one spam into my inbox per month. In the past I would use catch all on my domain and give addresses like adobe.com@<my-domain> to companies. It led to some fun stories like when I started getting a lot of spam to adobe.com@<my-domain> and Adobe support (I have been paying customer -- no more) claiming that they have absolutely not lost any of my information even though I could positively verify my adobe.com@<my-domain> address and password was available in one of publicly available databases. Nowadays I am using more and more SSO + MFA and it kind of makes that pattern less useful.
