     new sfValidatorEmail(array('required' =&gt; true, 'trim' =&gt; true)),
     new sfValidatorString(array('required' =&gt; true, 'max_length' =&gt; 80)),
     new sfValidatorDoctrineUnique(array(
       'model' =&gt; 'sfGuardUserProfile',
       'column' =&gt; 'email'
     ), array(
       'invalid' =&gt; 'An account with that email address already
  exists. If you have forgotten your password, click "cancel", then "Reset
  My Password."'))
   )));
  </code></pre>

  'You must write your e-mail').</p>
