As discussed in a thread back in 2011 (see: https://www.componentpro.com/qa/emailvalidator-doesnt-validate-info-domains) the top-level-domain (TLD) of an e-mail address can be more than 3 characters.
This is even more true now a days that TLDs aren't as restricted as they once were.
See: https://en.wikipedia.org/wiki/List_of_Internet_top-level_domains
Please change the default EmailValidator.EmailSyntaxPattern (see: http://www.componentpro.com/doc/emailvalidator/ComponentPro.Net.EmailValidator.EmailSyntaxPattern.htm) to match today's world.
