RegexLib.com ( http://regexlib.com/Search.aspx?k=email ) has hundreds of email validation routines for a reason. I'd recommend you read this article: http://www.unwrongest.com/blog/email-validation-regular-expressions/ and if you decide to continue using regex for validation, my favorite testing utility is the free regex designer available for free here: http://www.radsoftware.com.au/regexdesigner/ ... test all emails in a LARGE list (available for free download or purchase ... or use your own current DB) to ensure your regex is acceptable within your constraints.

I would recommend a basic test (many at the top of regexlib.com ... I'm not taking credit for the work of theirs I use routinely), followed by a email validation routine that requires user interaction. It is the only real way to 'validate' an email address.
