I’m absolutely in the “don’t self-host email” camp.
That said, I think it could be done reliably if you wanted to use someone else’s SMTP server and let them worry about deliverability. As in, have your mx records on your domain route to your MTA and dovecot, but set your DKIM and SPF records to match a third party SMTP server.
You could use mxroute as an SMTP server very cheaply. There are others like the email API type services.
I still can’t think of why I’d want to self host with all this drama but just an idea I’ve heard.
