That's true sending email from my MS Outlook box to my own gmail. At some point, it comes down to just doing the best you can and not stressing too hard.
Getting a dedicated server with an ISP that does a decent job at keeping their IP blocks clean for email is about the best you can expect. Setup the appropriate SPF/DKIM/DMARC and get along. There's really not too much more to be done these days. Even the big guys don't always get along.
