My understanding is that what you're looking for isn't available any
more. You used to be able to send a command to a mail server and get a
response back indicating if the address was valid or not. Spammers
caught on to that, however, and abused it to farm addresses, so most
email servers now ignore the command. You may have luck with some older
mail servers, but it's definitely not 100% reliable.

I have a client with an e-mail sign-up form on their site. In addition
to validating the syntax, they want to be able to determine on-the-
spot if the entered e-mail address is legitimate. I've come across a
couple of forms recently that do that but I can't remember where they
were.
I did find the following PHP code:
http://code.google.com/p/php-smtp-email-validation/
. However, I haven't been able to successfully implement it (I'm a
front end developer, not a programmer, and nothing I've tried has
worked). Has anyone had any success with this or another solution?
Thanks!
