推荐答案

您收到的错误意味着连接是在此行失败： SMTP.Connect（）。

The error that you are receiving means that the connection is failing on this line: SMTP.Connect().

通常，这意味着端口错误，服务器没有连接，或者您没有连接。

Usually, it means the port is wrong, the server is not up, or you don't have connectivity.

在这种情况下，您没有连接，很可能是因为您的ISP阻止连接到该远程端口

In this case, you don't have connectivity, most likely because your ISP is blocking connection to that remote port.

尝试从托管的网络服务器发送电子邮件。

Try sending the email from your hosted web server.

即使你可以连接，你的代码也赢了按照原样工作。 Google SMTP服务器端口465需要安全（SSL）连接。你仍然需要实现。看看：我如何使用Gmail的SMTP和Indy 10发送电子邮件？

Even if you could connect, your code won't work as is. Port 465 on Google's SMTP server requires a secure (SSL) connection. You'll still need to implement that. Take a look at: How do I send e-mail using Gmail's SMTP and Indy 10?
