Is there a way to validate an external e-mail address? I have over 4000 e-mail addresses, for example; joe@aol.com. How can I programmatically “ping” or check to see whether that is a valid e-mail that will not be rejected?
Thanks for any help.

How can anybody but aol.com know, if joe is a valid user as of today? Unlike the DNS brings together host names and IP addresses, there is no central repository for email addresses (luckily). Spammers would love such a feature.
