Either this, or you can write a quickie SMTP client.. if they type in
sk***@yahoo.com (sorry if this is someone's email) - you can attach
yahoo.com and do something like EHLO, then RECP sk***@yahoo.com and it will
return whether the email is valid or not.. this is slow, and not reliable -
as there is no gaurantee of what version/standard thier mail server adhere's
to....

No, there really no easy way to check on that - unless you try to send an
email to the address and wait to see if it bounces back.

If you are really concerned that somebody registering on your site is using a valid email address, just send them their password via the email address
provided, or something similar. I'm sure you've run across websites that do that as part of a registration.
