Missing a provider?
mailintel resolves any domain that publishes MX records. If the settings aren't known, the result says so instead of guessing — and you can add them with a pull request.
Detection
Don't know which one you're on?
Paste any address and mailintel reads the MX records to tell you the provider — even on a custom domain.
