问题描述

不允许使用邮箱名称.服务器响应为:很抱歉，您所在的位置[xxx.xx.xx.xxx](#5.7.1)
拒绝中继

我使用需要发送邮件的网页，使用下一个代码，但收到上述错误

Mailbox name not allowed. The server response was: sorry, relaying denied from your location [xxx.xx.xx.xxx] (#5.7.1)

string emailFrom = "[e-mail]";
            string emailTo = "[e-mail]"; 
            MailMessage mm = new MailMessage();
            mm.From = new MailAddress(emailFrom);
            mm.To.Add(new MailAddress(emailTo));
            mm.Subject =  txtEmpNameAr.Text;
            string body = txtEmpNameAr.Text.Trim() + "\n";
           
            body += txtNotes.Text.Trim();


            mm.IsBodyHtml = true;
            mm.Body = body;// txtNotes.Text.Trim();
            const string SERVER = "relay-hosting.secureserver.net";
            SmtpClient Client = new SmtpClient(SERVER, 25);
            Client.DeliveryMethod = SmtpDeliveryMethod.Network;
            Client.Credentials = CredentialCache.DefaultNetworkCredentials;
            Client.Send(mm);

我认为您的托管服务器存在问题，因为许多服务器不允许发送电子邮件的某些代码，而它们已经开发了仅用于发送的特定代码.因此，请联系托管服务器.他们会为您提供代码.

I think there is an issue from your hosting server because many servers not allowing some code for sending email they have developed some specific code that only used for send. So contact hosting server. They will provide you code for do so.
