      public class EmailValidator
      extends RegexFieldValidator

  EmailValidator checks that a given String field, if not empty, is a valid email address. The regular expression used to validate that the string is an email address is:

       \\b^['_a-z0-9-\\+]+(\\.['_a-z0-9-\\+]+)*@[a-z0-9-]+(\\.[a-z0-9-]+)\*\.([a-z]{2,6})$\\b

  You can also specify expression, caseSensitive and trim params as a OGNL expression, see the example below.
  - fieldName - The field name this validator is validating. Required if using Plain-Validator Syntax otherwise not required
  Check also documentation of the RegexpValidator for more details - the EmailValidator bases on it. Do not use ${regexExpression}, ${caseSensitiveExpression} and ${trimExpression} as an expression as this will turn into infinitive loop!

           <!-- Plain Validator Syntax -->
           <validators>
               <validator type="email">
                   <param name="fieldName">myEmail</param>
                   <message>Must provide a valid email</message>
               </validator>
           </validators>

           <!-- Field Validator Syntax -->
           <field name="myEmail">
              <field-validator type="email">
                 <message>Must provide a valid email</message>
              </field-validator>
           </field>

           <!-- Field Validator Syntax with expressions -->
           <!-- Only available when used with xml based configuration, if you want to have the same
                   flexibility with annotations use @RegexFieldValidator instead -->
           <field name="myEmail">
              <field-validator type="email">
                 <param name="regexExpression">${emailPattern}</param> <!-- will be evaluated as: String getEmailPattern() -->
                 <param name="caseSensitiveExpression">${emailCaseSensitive}</param> <!-- will be evaluated as: boolean getEmailCaseSensitive() -->
                 <param name="trimExpression">${trimEmail}</param> <!-- will be evaluated as: boolean getTrimEmail() -->
                 <message>Must provide a valid email</message>
              </field-validator>
           </field>
