The above code doesn't work. It lets through the following invalid email addresses:

  • .[email protected] (email cannot start with a period)
  • tyler@foocom (no period between domain and tld)
  • [email protected] (invalid tld)

Also, your regex is limiting the use of many other ASCII characters that RFC-2822 allows in an email address.

See http://www.ilovejackdaniels.com/php/email-address-validation/ for the proper way to do RFC 2822 validation.
