Ok so as much as I promote self-hosting email, you're right. I've also had trouble with mail originating on my server to gmail and only gmail accounts. I did recently discover that I had some configuration issues via mail-tester.com though (my rDNS didn't match the HELO of my server) so now that I'm getting a 10/10 on that, things seem a bit better. I definitely felt that gmail was being too aggressive on this too. I sent a bunch of detailed replies to middle/high schoolers working on science projects when they reached out through my public-education webpage and when they went to gmail I never got a reply but if they went to some other server, the conversations usually continued nicely. That was pretty frustrating.
