在一个网站，我工作，我只是需要它来发送电子邮件到几个地址，我的code正常工作在我的本地和使用远程邮件服务器发送的电子邮件。然而，当我发布网站的服务器我得到这个异​​常：

On a website I was working on I simply need it to send a email to a few addresses, my code works fine on my localhost and send the emails using the remote mail server. However when I publish the website to the server I get this exception:

命令的次序错误服务器响应为：试图发送到非本地电子邮件地址时，该邮件服务器需要身份验证，请检查您的邮件客户端设置，或与管理员联系以验证该域名或地址定义此服务器。

"Bad sequence of commands. The server response was: This mail server requires authentication when attempting to send to a non-local e-mail address. Please check your mail client settings or contact your administrator to verify that the domain or address is defined for this server."

下面是我的code：

SmtpClient client = new SmtpClient("mail.domain.com", 25);
                client.Credentials = new NetworkCredential("default@domain.com", "password
                client.UseDefaultCredentials = false;
                MailMessage message = new MailMessage();
                foreach (string address in db.Administrators.Select(e => e.Email))
                    message.To.Add(address);
                message.From = new MailAddress(email.FromEmailAddress);
                message.Subject = email.Subject;
                message.Body = email.Message;
                client.Send(message);

有其他人有这个问题？它是GoDaddy的具体点吗？

Has anybody else had this issue? Is it GoDaddy specific?

谢谢， 亚历克斯。

推荐答案

只需使用此

MailMessage m = new MailMessage("default@domain.com", "to", "subject", "body");
m.IsBodyHtml = true;
SmtpClient smtp = new SmtpClient("relay-hosting.secureserver.net");
smtp.UseDefaultCredentials = true;
smtp.Send(m);

我就同样的问题，面对几个月前它的工作对我来说...

i had same problem faced couple of months ago it worked for me...
