The only way to do that is by sending an e-mail and having the user click a link to validate the address is real, and theirs.
 
Since this a very common thing to do, there a some good articles about it. This was the top hit for me on Google: http://ctrlf5.net/?p=55[^]
 
Hope this helps Smile | :)

What is your scene, hard to Guess.
 
If you want to check the Email ID user entered is Valid (means exists) or not.
 
I know the Great way to do so.
 
Send mail to ID and wait for Bounce Mail. If you Receive any Bounce Mail from Server then it does not Exist, otherwise It Exists.
 
lol...
 
If you want to check in your Database, whether this email id has registered earlier or not. This is also simple, check at the time of Registering.
 
If other is your case, please tell us...
 
If you want to Check the User entered Valid Email Id or Not. Answer 1 is posted above.
