Comment:
Except that per RFC 822 (http://www.w3.org/Protocols/rfc822/Overview.html), the following email addresses are valid but would be trapped as invalid by this code. Specifically, look at Appendix A (http://www.w3.org/Protocols/rfc822/Overview.html#z10), section A.3.3.<br><br> "Some Silly User"@example.com<br> Another'User@example.com<br> Yet/Another/Wacky/User@example.com
