Why email_address say is false for simple valid address [email protected]? about email_address HOT 3 CLOSED

This is because the gem validates the domain's Mail Exchanger (MX) DNS records. example.com has no MX and is unable to accept email. The syntax of the email is correct, but the email address will not work. You can turn off DNS lookup to get the address to pass validation.

EmailAddress.error("[email protected]")
=> "Invalid Host/Domain Name"
EmailAddress.valid?("[email protected]", dns_lookup: :off)
=> true

@afair, you are a wizard!
Thank you very much.
I promise, always, always carefully read the documentation, and only then ask questions!

@tit It was a good question! The documentation is terse for starter usage. That should get better in the next releases.
