Except... Gmail has handled spam pretty well? And at least if you do get Spam they actually tell you: https://news.ycombinator.com/item?id=6090712
I ask because I haven't yet bothered to implement it on a from-scratch email server I stood up a couple weeks ago (just kidding; I wanted to brag about SPF, DKIM, and DMARC test passes from Gmail with both inbound and outbound encryption). I can say from this experimentation and using Google's Postmaster tool, though, that emails being reported as spam by users is *very* serious; Google's threshold is 0.3%; if just 0.3% of users report your email as spam, it's considered a policy violation and your emails are likely to go to spam or have delivery refused outright. idk what Proton's policies are. (edit: by extension, this means enforcing authorization of users is very serious; if someone abuses the service as an open relay, your whole domain is toast)
Other than that I’m a happy paying customer.
I guess I can't have important announcements from Proton in the future if it's polluted with these low value messages.
It made me move to Mullvad.
Despite the fact that in terms of performance Proton is slightly better. (underscoring just *how* crucial ‘trust’ is)
