Pretty much anything you'll find recommended can receive mail fine. Consistently delivering it is another job you/I, and most people, probably don't want. Maybe that Super Important email you sent got delivered. Maybe it didn't. If not, maybe it bounced. Maybe it didn't, and so on. Life generally doesn't get easier adding services to admin. Especially one as trusting, yet not, as email. IP reputation, blacklists, whims of some remote greybeards, etc. I've done it before and it went well. Then it didn't and I took stock. Entirely not worth it. Dedicating time to decorate and maintain a trash bin. All told: I'm entirely happy to pay someone else to host this. I put my sensitive stuff on services I run that are also easier to get consistency out of
