从服务器smtp发送邮件时出错

Question

我的邮件发送代码如下，已托管在服务器上：

try
    {
        MailMessage msgMail = new MailMessage();
        MailMessage myMessage = new MailMessage();
        myMessage.From = new MailAddress("*****");
        myMessage.To.Add(TextBox1.Text);
        myMessage.Subject = "Subject";
        myMessage.IsBodyHtml = true;
        myMessage.Body = "Message Body";

        SmtpClient mySmtpClient = new SmtpClient();
        System.Net.NetworkCredential myCredential = new System.Net.NetworkCredential("email", "password");
        mySmtpClient.Host = "****";  //Have specified the smtp host name
        mySmtpClient.UseDefaultCredentials = false;
        mySmtpClient.Credentials = myCredential;

        mySmtpClient.Send(myMessage);
        myMessage.Dispose();
    }
    catch (Exception ex)
    {
        Response.Write(ex.ToString());
    }

我不断得到这个错误

System.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: #5.1.0 Address rejected [e-mail] at System.Net.Mail.SmtpTransport.SendMail(MailAddress sender, MailAddressCollection recipients, String deliveryNotify, SmtpFailedRecipientException& exception) at System.Net.Mail.SmtpClient.Send(MailMessage message) at Mail.Button1_Click(Object sender, EventArgs e) in d:hosting9110120htmlFBMail.aspx.cs:line 37

我什么都试过了。它不断给出相同的错误

我的网站托管在Godaddy服务器上

Answer 1

您的代码似乎很好，显然可能是您需要对其进行配置：http://support.godaddy.com/help/article/5444

Answer 2

它失败了，因为电子邮件地址不存在。只要处理这个异常，你就应该做好准备了。

如何在不发送电子邮件的情况下检查电子邮件地址是否存在？

Answer 3

我也遇到了同样的问题，通过在下面的行中做一个小的更改来解决它

System.Net.NetworkCredential myCredential=新的System.Net.NNetworkCredential（"电子邮件"、"密码"）；

验证您的凭据，这对我有效：）。。
