I doubt the validity of those automated checks and checks on the email
anyway. What constitutes "owning" foo at example.com? To legitimately
verify this you would need to look at the domain history, conclude who
the legit owner of the domain is, contact that owner and then follow the
delegation chain to reach a real person.
Any technological solution to the problem is easy to compromise:
Accounts can be compromised, domains stolen, DNS isn't safe either and
the mail server could be penetrated. The only way to know if someone
legitimately uses a given email address is to verify the _human_
delegation chain. A computer cannot do that in the current setup.

No situation is so dire that panic cannot make it worse.
