I think that was his plan...here is the simplified version:

** RFC 2822 (Simplified)
.Pattern = "[a-z0-9!#$%&'*+/=?^_`{|}~-]+" +;
           "(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*" +;
           "@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+"+;
           "[a-z0-9](?:[a-z0-9-]*[a-z0-9])?"

;-)

(Note: I didn't figure this out...it is one of the many samples that comes with RegEx Buddy)
