Re: Verifying E-Mail Addresses

The "best-effort" I can think of is to verify that the domain part is correctly configured for e-mail in DNS. This can be achieved by looking for an MX record for the 'company.com' domain. One of my clients does just this on some web sign-up forms they have.

Hello list,

Is there a way to verify that an e-mail address
(e.g."johnsmith () company com") is valid and exists or does not exist
(is a fake e-mail address) without actually sending a message to that
address and awaiting the response?
