* Google Is Eating Our Mail
https://news.ycombinator.com/item?id=19756125
My personal mail server has all the industry-standard SPF, DKIM, and DMARC records. But Google still randomly eats my mail, and the system gives no explanation, sometimes it was my kernel patches submitted to the Linux maintainers, yikes! Weeks of time wasted.
Do you (or anyone) happen to know how the big players (AWS SES, SendGrid, Mandrill etc) work around this issue? I understand they offer dedicated IP address, but I suppose a considerable amount of their emails goes through the "shared pool".
Maybe a high volume of sends actually helps?

The good thing is, I've hosted emails on my personal server for 4 years or so, and I don't have any issue so far, as long as it's not Google, but it's probably not so assuring to you because of this exact reason...

The unfortunate result of machine learning? I guess Google's spam filter has lots of pattern-matching and heuristics that don't follow "the rules of E-mails" exactly. Anecdotes in the comments I linked says Google's spam filter has became more aggressive in recent years, I suspect it must be ML.
I hope other HN readers can give a more informative answer to your post, as a sender, I'm having the same problem, it's two sides of the same coin...
