is it the right reqular expression
<p>i have following regular expression but it's not working properly it takes only three values after @ sign but i want it to be any number length</p>

<p>"/^[a-zA-Z0-9_.-]+\@([a-zA-Z0-9-]+.)+[a-zA-Z0-9]{2,4}$/"</p>

<p>this@thi        This is validated
this@this       It is not validating this expression</p>

<p>Can you please tell me what's the problem with the expression...
Thanks</p>
