Don't have to run your own mail server, nor would your mails be rejected necessarily... There are a lot of providers around which let you use your own domain.

Don't have to run your own mail server, nor would your mails be rejected necessarily... There are a lot of providers around which let you use your own domain. And if you're using your own domain, you're always able to switch providers by updating your mx records. But I wouldn't ask my family to do that either, that's just something for tech enthusiasts and people that make their actual living by being reachable through mail (contractors etc)
