This is just a shot! What I want to do on my web page is to allow a signed in user to provide his email address. I want to programmatically determine if this is a valid email, does it actually exist not just determine if it is validly formatted. I know DASP supports and provides email service but as part of that is there a utility that will allow me to programmatically determine an email address's validity. Perhaps I could send a friendly sign up message and retrieve an error code.
