Answer 1

Try this,

function validate()
{
    jimport('joomla.mail.helper');

    $valid = true;

     if ($this->_data->email && !JMailHelper::isEmailAddress($this->_data->email))
    {           
         $this->_app->enqueueMessage(JText::_('Invalid Email Address'),'error');                       
         $valid = false;           
    }   
    return $valid; 
}

Answer 2

{
jimport('joomla.mail.helper');

       $error   = false;
if (! $email  || ! JMailHelper::isEmailAddress($email))

    $error  = JText::sprintf('Email Corect', $email);
    JError::raiseWarning(0, $error);
}

 return $error;
}
