Moving away from Gmail isn't that hard. It's on my list forever, but an Subscription to O365 and an IMAP migration is both great because: A: You're paying Microsoft for a service, and that has many more features than gMail. B: I believe Microsoft is more transparent than Google. C: You remove the identity (IAM) part of Google from your Email and separate yourself from Google's Ecosystem. D: Finally doing an IMAP migration gives you an independent copy of all your email to date. You can also download all your data from Google too, through some obscure settings page. Having your own domain. Enable SPF. Enable DMARC/DKIM if you dare. Enable hard failure on SPF. All that you need. Running your own server is HARD there are projects that make it easier like mailinabox, but it is HARD and annoying work. If you ever want to see how annoying it can be, load up shodan.io and just look up postfix CVE + postfix version numbers. Granted O365/Exchange is it's own thing and can become a headache, but there is tons of support available and it's meant to be portable and easy to move away from. gMail is Google. Google is designed to trap you in forever. :(
