EmailValidator

public class EmailValidator (Code)

Perform email validations.

This class is a Singleton; you can retrieve the instance via the getInstance() method.

Based on a script by Sandeep V. Tamhankar http://javascript.internet.com

This implementation is not guaranteed to catch all possible errors in an email address. For example, an address like nobody@noplace.somedog will pass validator, even though there is no TLD "somedog"
