I was sure that there was an FAQ about this that basically said you can't just for the reasons that Rob has said. Email addresses of all kinds can be valid [EMAIL PROTECTED] is a valid email address according to RFC822 but in practise will probably be undelivered. Formbuilder and HTML::FormFu have email validation pattern. Perhaps the better solution is to get the user to confirm the email address in a 2nd field.
