I've spent many, many hours playing with my mailserver and adding all of these extra features and security settings to try to keep Gmail and others from denying mail from me. It turns out that no matter what I do, I'm pretty much out of luck because I'm sending from a non-standard (.link) domain which gets treated as spam by Gmail as well as others. I get a perfect score on every email test site I've tried, but I still go to spam (or worse) regularly which is a big problem if I ever want to use my personal email for anything important. For anyone looking to host their own email using a personal domain, I'd suggest sticking to something like .com to avoid the hell that I've been through with this.
