cakePHP和邮件组件:拒绝连接:61

问候语! 我正试图将简单的邮件功能添加到一个小web应用程序中,但我被卡住了。我可以在本地机器上从终端向自己发送电子邮件,但当我尝试运行应用程序时,我得到“连接被拒绝:61”

$this->Email->smtpOptions = array(
   'port'=>'25',
   'timeout'=>'30',
   'host' => 'user-power-mac-g5.local',
   'username'=>'',
   'password'=>'',
   'client' => 'user@users-power-mac-g5.local'
)

$this->Email->delivery = 'smtp';

$User = "some user"; 
$this->Email->to = 'user@users-power-mac-g5.local';

$this->Email->subject = 'Welcome';
$this->Email->replyTo = 'user@users-power-mac-g5.local';
$this->Email->from = 'Web App <user@users-power-mac-g5.local>';
$this->Email->sendAs = 'text'; 
$this->set('User', $User);
$this->Email->send();
$this->set('smtp-errors', $this->Email->smtpError);

我试图在XAMPP上使用CakePHP1.2.5运行它,并且只运行核心邮件组件。 提前谢谢!
