Sorry, I'm not always good at putting my questions down in words.

From msdn.com

"If you are distributing reports within an intranet and you are using an SMTP gateway to a Microsoft Exchange server, type the e-mail alias (as if you were sending e-mail to a coworker)."

The RS automatically populates the email address field with the username of the individual logged on. It is just not working on my current setup and I do not know where to look to resolve this. It has worked for me in the past at other companies I have worked at.
