check (also) for email providers to determine if valid email is /not/ a company address

Hello,
https://gist.github.com/ammarshah/f5c2624d767f91a7cbdc4e54db8dd0bf
maintain a list of email providers (free, paid...)

could we add a second validation like
isFromProvider (if isValid) to check if the email is (not) a company address

The interest to implement it on mailchecker is that no more tools will be needed
Of course, if you seems that this idea is interesting, I can create a PR
