未在cronjob sugarCRM中发送电子邮件

我已经成功地从我的本地主机使用gmail设置了电子邮件设置，我的sugar实例正在发送测试邮件。我还完成了cron作业设置并进行了测试。 当我尝试在无法发送的cron作业中发送电子邮件时，就会出现问题。我使用的基本代码是

    require_once('include/SugarPHPMailer.php'); 
    $emailObj = new Email();
    $defaults = $emailObj->getSystemDefaultEmail();
    $mail = new SugarPHPMailer();
    $mail->setMailerForSystem();
    $mail->From = $defaults['email'];
    $mail->FromName = $defaults['name'];
    $mail->Subject=from_html($bean->name);
    $mail->Body="hello this is testing ....!";
    $mail->prepForOutbound();
    $mail->AddAddress('abc@yahoo.com'); 
    @$mail->Send();

以下错误显示在致命日志中

09/24/12 10:58:07 [4560][1][FATAL] SMTP -> ERROR: EHLO not accepted from server. Code: , Reply:

有时它会给出下面的一个

  09/24/12 11:01:07 [832][1][FATAL] SugarPHPMailer encountered an error: Language string failed to load: tls

有人能帮忙吗？

您能确认系统电子邮件设置设置是否正确吗？看起来似乎不是。是的，设置了电子邮件设置，我通过发送测试邮件确认。您在这里看到任何PHP错误吗？我在想，默认的电子邮件设置是如何加载的。
