A MX record is not necessary for a host to be able to receive email.
- oinksoft 14y agoNote that that library can also check for an MX server. It goes Valid string -> MX exists -> User exists (you can choose to only check for MX, or only for valid string).
- michaelmior 14y agoReally? How is mail routed then?
- emillon 14y agoIt should fall back to a A record. That's not exactly best practice, but if you're compliant that is something that you should be able to handle.
