checking if email adresses exist

Hey all,

I'm going to make an option for people to add email adresses to a database.
I know how to validate them stringwise ( something@something.com).
I would however like to check if they exist, without confronting the user
with some sort of registration email.
Is there a way to see if an email bounces without sending something to the
user?

Thanks,
Tim

A good article on email validation in PHP is located at
http://www.zend.com/zend/spotlight/ev12apr.php. It wouldn't be that hard
to extend the functionality into whatever language you're using.
