The RegexValidator created by Email->getEmailValidator should be given a message similar to the EmailAddress validator, rather than the obnoxious dump of the pattern.
The EmailAddress validator also handles IDN hostnames, while the regex here blocks them.
A comment says that the regex is to match HTML spec behavior - either Firefox and Chrome allow IDN hostnames though.
