"C:\ Inetpub \ mailroot \ Queue"

您可能在上述路径中有两条消息.

您可能需要检查SMTP服务器.首先确保它正在运行，然后检查其权限或是否需要身份验证.有时，如果某个地址没有MX记录，则可能会导致问题.

您还应该尝试删除第一条消息，因为它们可能阻塞了队列.还要检查电子邮件地址是否确实存在.

"C:\Inetpub\mailroot\Queue"

You might be having two many messages in the above mentioned path.

You probably need to check your SMTP server. Firstly make sure it is running and then check its permissions or whether it needs authentication. Sometime if an address does not have an MX record, this can cause a problem.

You should also try deleteing the first messages as they may be blocking up the queue. Also check that the e-mail address actually exists.
