无法向电子邮件发送消息

我在服务器上发送消息时遇到问题。但在我本地，我可以使用免费的 smtp 服务器向电子邮件发送消息。

也许存在防火墙或电子邮件策略不接受本地主机？

请指教..谢谢！

代码：

//send email
MailMessage objEmail = new MailMessage(new MailAddress(ConfigurationManager.AppSettings["emailAdd"].ToString()), new MailAddress(ConfigurationManager.AppSettings["emailAdd"].ToString()));
objEmail.Subject = "Test";
objEmail.Body = _Message;
objEmail.Priority = MailPriority.High;
SmtpClient SmtpMail = new SmtpClient();
SmtpMail.Host = "localhost";
SmtpMail.Send(objEmail);

错误：

System.Net.Mail.SmtpFailedRecipientException：邮箱不可用。服务器响应为：5.7.1 无法中继[电子邮件受保护] 在System.Net.Mail.SmtpTransport.SendMail（MailAddress发件人，MailAddressCollection收件人，字符串deliveryNotify，SmtpFailedRecipientException＆异常）在 System.Net.Mail.SmtpClient.Send(MailMessage 消息)

I having problem on sending message on the server. But in my local I can send message to the emails using the free smtp server.

Maybe there's a firewall or localhost is not accepted in the email policy?

Please advise.. thanks!
