推荐答案
这很可能表明你没有任何正确的主机名，或正确的端口。
This most likely indicates you don't have either the correct host name, or the correct port.
如果您使用的是SSL，则默认SMTP端口是25将无法正常工作。我注意到，你也有一个线路设置什么注释掉的端口。
If you are using SSL then the default SMTP port which is 25 will not work. I noticed that you did have a line setting the port what was commented out.
尝试设置端口为587，如果还是不行，请尝试端口465是有时用于安全SMTP。
Try setting the port to 587 and if that doesn't work, try port 465 which is sometimes used for secure SMTP.
如果不工作，要么与你的客户正确的端口和主机名确认。
If that doesn't work either confirm with your client the correct port and host name..
和你可能想仔细检查另一件事是您正在使用的SMTP服务器是否确实如此支持/要求SSL。如果它不支持SSL，你将需要设置 EnableSSL 选项设置为false，并尝试连接的25（或任何端口他们使用）的默认端口。
And another thing you may want to double check is whether the SMTP server you are using does indeed support/require SSL. If it does not support SSL that you will need to set the EnableSSL option to false and try connecting on the default port of 25 (or whatever port they are using).
