推荐答案

您是否尝试

此错误的可能原因是 Smtp.Mail无法找到您的交换服务器.尝试检查防火墙上是否配置了Exchange Server的端口25.

另外，请先尝试设置
SmtpMail.SmtpServer="localhost";
在开发机器上.它应该工作.

此外，尝试在SmtpServer属性中指定IP地址而不是名称.

The possible cause of this error is Smtp.Mail unable to locate your exchange server. Try checking the firewall for port 25 on which the Exchange server is configured.

Also, first try setting
SmtpMail.SmtpServer="localhost";
on the development machine. It should work.

Further, try specifying IP Address instead of name in SmtpServer property.
