Email Validation

[Ramadoss Chinnakuzhandai <rc...@register.com>]

Hi,
         I'm using custom email validation using mask defined in my validation.xml...when I enter an invalid email as xyz@.xyz.com it fails to validate the . (dot symbol infront of xyz.com) as a invalid one though I metioned expression value must be of [A-Z0-9a-z] after @

Following is my regular expression 

<constant>
	<constant-name>emailAddress</constant-name>
	<constant-value>^[A-Z0-9a-z_]+(.)?[A-Z0-9a-z_]+@[A-Z0-9a-z]+(.)?[A-Z0-9a-z%-]+\.[A-Za-z]+(.)?[A-Za-z]{2,4}$</constant-value>
</constant>

Following is the field ccEmail 

<field property="ccEmail" depends="required,mask">
	<arg0 key="form.email"/>
	<msg name="mask" key="errors.email"/>
	<var>
		<var-name>mask</var-name>
		<var-value>${emailAddress}</var-value>
	</var>
</field> 


Can anybody correct me where I'm doing wrong or suggest me any better approach.

Thank you,

-Ramadoss


Note: I tried build-in email validation but still I'm able to enter invalid email address and proceed.
