Dont know about the PEAR implementation but I use

	function check_user_email($email, $check_dns = false){

		if((preg_match('/(@.*@)|(\.\.)|(@\.)|(\.@)|(^\.)/', $email)) || (preg_match('/^.+\@(\[?)[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,3}|[0-9]{1,3})(\]?)$/', $email)))
  		{
    		if($check_dns)
    		{
      			$host = explode('@', $email);
      			// Check for MX record
      			if( checkdnsrr($host[1], 'MX') ) return true;
      			// Check for A record
      			if( checkdnsrr($host[1], 'A') ) return true;
      			// Check for CNAME record
      			if( checkdnsrr($host[1], 'CNAME') ) return true;
    		} else {
      			return true;
    		}
  		}
  		return false;
	}
