Email validator

This is a small library which can be used to validate email addresses.

Rather than use convoluted regular expressions, or maintain a list of valid TLDs, etc, to validate the domain part of the email address, it performs a DNS lookup. If it has an MX, A, or AAAA record, the domain part is considered valid.

Usage:

if (EmailValidator.isValidEmailAddress("[email protected]")) {
   // Do a happy dance
} else {
   // Sad face.
}
