if (!$this->getIsConnect() && $this->bolIsLogin)
{
return false;

$this->sendCommand("QUIT");
$this->getLineResponse();
if (!$this->getRestIsSucceed())

}
return true;
}

//獲取郵件數量和字節數(返回數組)
function getMailSum($intReturnType=2)

$strLineResponse = $this->getLineResponse();
if (!$this->getRestIsSucceed())
{
return false;
}
if ($intReturnType==1)

}
else
{
$arrResponse = explode(" ", $this->strResponse);
if (!is_array($arrResponse) || count($arrResponse)<=0)

return array($arrResponse[1], $arrResponse[2]);
}
}

//獲取指定郵件得Session Id
