All professional and personal eMail through gMail?
Oof, buddy. That cock-up is on you. Even if you don’t want to administer your own iron, there are plenty of third-party services that can host your eMail domain.
And with a little work, there is eMail-in-a-box for a turnkey solution, and others like hMailServer if you just want a minimalistic low-effort server running on an old Windows box in your basement.
No it's not.
The absolute vast majority of professional and personal emails go through the big 3, Gmail, Yahoo, msn/hotmail/outlook.
What we need is better laws to ensure email is treated similar to utilities with strong consumer protection and appeal system, not victim blaming.
I’m talking about not putting all your eggs into one basket. Of which OP’s nightmare is the perfect example.
I wouldn’t lean on a Gmail eMail when building Android apps in the same way I wouldn’t lean on an iCloud eMail when building iOS apps. If they get ticked off at you, they can cause you to lose everything. They can pull the rug out from under you at a moment’s notice. And while I have accounts under both, they’re throwaways that only see use as backup eMail.
It’s why you always need to fully separate your concerns. Use a third-party hosting that won’t otherwise skullf*k you because of something you have done elsewhere or with a service they don’t own. I mean, if they don’t own that service, why would they shaft you?
Which countries are you thinking about? Honestly haven't seen a company in the EU self hosting email for probably 15 years, and I used to run the email server at a company.
Self-hosted mail servers are not common anywhere. Smaller providers are more common in some places. Small provider isn't the same as self-hosted; neither is enterprise.
There are still countless exchange servers running in the default enterprise MS setup. Perhaps not for long since MS nudges people into their cloud, but they are still fairly common.
