I wanted to know how to check if an email exists / is real. I’m making a website (in Asp.net), which for the person to do "Register", has to enter an email and a password. But how do I check if the email is real? I know I could check if you have any "@" or ". with" or something like that, but the email may not exist.

the only way I see it is you force the guy to validate the email... make the registration but before you allow access the guy has to go in the email and validate... either by entering a code or accessing a link that only got by the email sent from your site to his email...
Okay, thanks, I’ll do it

Why don’t you do as all the sites do and send an email with a confirmation link? If the user does not click the confirmation link you assume that the email is invalid, simple like this

It usually checks if Emal is valid on the client side but to check if it actually exists you would have to communicate with the email service itself, understand? Will it only be a domain used by your application? If it is more than one believe it will take a little more work.
