Within asp.net I know it is possible to validate that a user has entered
in a correctly formatted email address. However, what I want to be able
to do is to verify that the email address entered is actually going to
work. As in that it will receive email.

I have been looking at one way to do this, and that is to see if the
domain part of the email address is a valid domain, but I was wondering
if there was a better way of checking to see if the email address
entered is actually valid.

Any suggestions appreciated on this subject. Thanks.
 
I think that may be you can ask the SMTP server. you may need to read some
RFC on SMTP protocol.

After experimenting with all sorts of convoluted approaches I first validate
the format (regular expression) and if valid I send an email to the
submitted address that includes a link that verifies that the email was
received. It works for me.
