我正在 Windows azure 云虚拟机中的 sql server 2012 上设置电子邮件选项。电子邮件不起作用，我收到以下错误：
Error,15,由于邮件服务器故障，无法将邮件发送给收件人。（使用帐户 2 (2012-07-02T11:13:17) 发送邮件。
异常消息：无法将邮件发送到邮件服务器。（远程证书根据验证程序无效。）。）,3152,5,,7 /2/2012 11:13:17 AM,sa 07/02/2012 11:12:05
,,错误,14,由于邮件服务器故障，无法将邮件发送给收件人。（使用帐户 2 (2012-07-02T11:12:05) 发送邮件。
异常消息：无法将邮件发送到邮件服务器。（根据验证程序，远程证书无效。）
我的 vm 上应该有一个端点 25 吗？还有什么可能导致此错误？
Looks like there is an issue with the outbound stmp server you are trying to use. Is this also hosted in Windows Azure or an external provider somewhere? In both cases, make sure they allow inbound, authenticated connections and on what port. There shouldn't be any blocks on outbound connections on your Windows Azure virtual machine, so odds are the problem is where the email server is hosted.
