如何仅使用IP地址发送邮件 [英] How Do I Send Mail Using Only Ip Address

问题描述

Hello House，



我正在处理需要发送邮件通知的项目，smtp服务器要求使用ip指定from地址，我已经完成了这和它工作，但要部署应用程序，我只给了一个IP地址，我试过发送只有IP地址的邮件，但它不工作，错误信息是：没有连接，因为目标机器主动拒绝它10.90.17.203:25



i怀疑邮件服务器需要某种身份验证，客户端坚持认为他只向其他供应商提供ip，而且他们有能够用它发送邮件。如果可以的话，我需要你的帮助。这是我的代码：

Hello House,

I am working on project that requires sending mail notifications, the smtp server requires that the from address be specified with the ip, i have done this and it is working, but going to deploy the application, i am only given an ip address, i have tried sending mails with only ip address but it is not working, the error message is: No connection could be made because the target machine actively refused it 10.90.17.203:25

i suspect the mail server requires some sort of authentication, the client insists that he gives only the ip to other vendors, and they have been able to send mail with it. Please i need your assistance, if this could be done. here is my code:

static void CreateMail(string recipient, string subject, string msg)
        {
            Configuration oConfig = ConfigurationManager.OpenExeConfiguration( ConfigurationUserLevel.None );
            var mailSettings = oConfig.GetSectionGroup( "system.net/mailSettings" ) as MailSettingsSectionGroup;
            //var mailAttachment = (System.Configuration.ConfigurationManager.AppSettings["MailAttachment"]);
            var mailRecipients = ( ConfigurationManager.AppSettings["MailRecipients"] );

            if (mailSettings != null)
            {
                //int port = mailSettings.Smtp.Network.Port;
                var from = mailSettings.Smtp.From;
                var host = mailSettings.Smtp.Network.Host;
                var pwd = mailSettings.Smtp.Network.Password;
                var uid = mailSettings.Smtp.Network.UserName;

                try
                {
                    var message = new MailMessage();
                    message.To.Add(recipient);
                    message.Subject = subject;
                    message.From = new MailAddress(from);
                    message.Body = msg;
                   // message.Bcc =bcc;
                    message.Priority = MailPriority.Normal;

                   
                    var smtp = new SmtpClient(host);
                    smtp.Credentials = new System.Net.NetworkCredential(uid, pwd);
                    smtp.Send(message);
                    smtp.Dispose();
                    Log.Info("Mail sent successfully to the following recipients: " + "\n\r\n\r " + mailRecipients);
                    //}
                }
                catch (SmtpException ep)
                {
                    Log.Error(ep.ToString() + "\n\n\r " + ep.StackTrace);
                }

            }

我的配置文件：

My Config file:

<system.net>
    <mailSettings>
      <smtp from="[e-mail]">
        <network host="192.168.0.100" userName="[e-mail]" password="Sirpic.80"/>
      </smtp>
    </mailSettings>
  </system.net>
