无法将消息发送到电子邮件 [英] Failed to Send Message to Emails

问题描述

我在服务器上发送消息时遇到问题.但是在我本地，我可以使用免费的smtp服务器将邮件发送到电子邮件中.

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.

电子邮件策略中是否存在防火墙或本地主机不被接受?

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

请告知..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无法为[e-mail]中继在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)

System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: 5.7.1 Unable to relay for [e-mail] at System.Net.Mail.SmtpTransport.SendMail(MailAddress sender, MailAddressCollection recipients, String deliveryNotify, SmtpFailedRecipientException& exception) at System.Net.Mail.SmtpClient.Send(MailMessage message)

推荐答案

This blog post answers basically the same question. Assuming you are sending through the IIS SMTP server, you may need to modify the Relay Restrictions to allow relaying from your IP address.
