我正在尝试从我的网站发送邮件:这是我后面的代码:

I''m trying to send mail from my site :here is my code behind :

MailMessage myMessage = new MailMessage();
       myMessage.Subject = "This is just for checking the EMail <N.n>";
       myMessage.Body = TextBox2.Text;
       myMessage.From = new MailAddress("[e-mail]", "mysite.com");
       myMessage.To.Add(new MailAddress(TextBox1.Text, TextBox1.Text));

       SmtpClient mySmtpClient = new SmtpClient();
       mySmtpClient.Send(myMessage);

这是我的web.config:

and here my web.config:

<system.net>
    <mailSettings>
      <smtp deliveryMethod="Network">
        <network host="smtp.mysite.com" userName="mysite.com" password="mypass" />

推荐答案

似乎您用于SMTP协议的配置导致中继操作(

It looks like the configuration you are using for the SMTP protocols are resulting in a relaying operation (http://en.wikipedia.org/wiki/SMTP_relay[^])

The majority of legitimate smtp server will not support open relaying due to the abuse that can occur from spamming.

You will need to configure your application to use an appropriate SMTP gateway, which will therefore probably require authentication to be added into the equation.

这意味着您必须在上使用帐户该服务器以发送电子邮件. 中继"是允许某人使用您的
的行为 服务器具有在服务器上找不到的发件人"地址.

What that means is that you have to use an account on that server in order to send emails. "Relay" is tha act of letting someone use your
server with a "from" address that is not found on the server.

必须以这种方式使用，伙计们，我用过它并且工作了！

Must use in this way guys,I used this and worked!

SmtpClient client = new SmtpClient("mail.somecompany.com", 25);

          // Configure the SmtpClient with the credentials used to connect
          // to the SMTP server.
          client.Credentials =
              new NetworkCredential("[e-mail]", "password");

          // Create the MailMessage to represent the e-mail being sent.
          using (MailMessage msg = new MailMessage())
          {
              // Configure the e-mail sender and subject.
              msg.From = new MailAddress("[e-mail]");
              msg.Subject = "hi";

              // Configure the e-mail body.
              msg.Body = "Hi.";

              // Attach the files to the e-mail message and set their MIME type.
              msg.Attachments.Add(
                  new Attachment(@"..\..\Recipe10-07.cs","text/plain"));
              msg.Attachments.Add(
                  new Attachment(@".\Recipe10-07.exe",
                  "application/octet-stream"));
}
client.Send(msg);
