Running a mail server is pretty difficult, especially if you're doing it on some public cloud offering. Even just keeping your IP off of blacklists can be frustrating and time consuming. Highly recommend letting someone else deal with that problem. I've been happily using Migadu (https://www.migadu.com/ https://www.migadu.com/) for a while. Maybe that's a good solution for you too.
