推荐答案

这通常意味着您不在网络上，您所连接的SMTP服务器已启用。通常，ISP会阻止这种情况，以防止网络外的人使用他们的电子邮件服务器发送垃圾邮件。



您通常必须与SMTP服务器位于同一网络中''试图使用。

It usually means that you''re not on the network that the SMTP server you''re connect to is on. Normally ISPs block this to prevent people from outside their network from using their email servers to send spam.

You normally have to be inside the same network as the SMTP server you''re trying to use.
