How to Validate E-mail Addresses

Here's a service program that checks the basic syntax of an e-mail 
address. It makes sure that the syntax of the address is legal and uses 
DNS to verify the domain portion (the portion after the @ symbol) of the 
e-mail address.

In addition to the service program, a test program is included showing 
how to call the service program. You can download the code here:
