Question

我有一个托管在Godaddy服务器上的Web应用程序。我被困在发送邮件错误。我把我的代码放在这里

public void Mailing()
{
 MailMessage message = new MailMessage();
 try
{
    MailAddress fromAddress = new MailAddress("mailadress@server.net");
    message.From = fromAddress;
    message.To.Add("toresive@server.com");
    message.CC.Add("ccresive@server.com");

    message.Subject = "Hello client";
    message.IsBodyHtml= true;
    string body = "Hello!<br> How are you?";

    message.Body = body;

    SmtpClient smtpClient = new SmtpClient();
    smtpClient.Host = "relay-hosting.secureserver.net";
    smtpClient.Port = 465;
    smtpClient.EnableSsl = false;
    smtpClient.UseDefaultCredentials = false;
    smtpClient.Credentials = new NetworkCredential("mailadress@server.net", "Password");
   // AdvancedIntellect.Ssl.SslSocket ssl = new AdvancedIntellect.Ssl.SslSocket();
    smtpClient.Send(message);
    smtpClient.Timeout = 10000;
    }
    catch (Exception ex)
    {
        label2.Text = ex.Message;
    }
}

}

但我收到了错误

System.Net.Mail.SmtpException：发送邮件失败。 ---＆GT; System.Net.WebException：无法连接到远程服务器---＆gt; System.Net.Sockets.SocketException：连接尝试失败因为关联方在一段时间后没有正确回应时间或已建立的连接因连接的主机而失败未能回应68.178.232.62:25 at System.Net.Sockets.Socket.DoConnect（EndPoint endPointSnapshot， SocketAddress（socketAddress）at System.Net.ServicePoint.ConnectSocketInternal（Boolean connectFailure，插座s4，插座s6，插座＆amp; socket，IPAddress＆amp;地址， ConnectSocketState状态，IAsyncResult asyncResult，Int32超时，异常和放大器;例外）---内部异常堆栈跟踪结束--- at System.Net.ServicePoint.GetConnection（PooledStream PooledStream，对象所有者，布尔异步，IPAddress＆amp;地址，插座＆amp; abortSocket，插座及放大器; abortSocket6，Int32 timeout）at System.Net.PooledStream.Activate（Object owningObject，Boolean async， Int32超时，GeneralAsyncDelegate asyncCallback）at System.Net.PooledStream.Activate（Object owningObject， GeneralAsyncDelegate asyncCallback）at System.Net.ConnectionPool.GetConnection（Object owningObject， GeneralAsyncDelegate asyncCallback，Int32 creationTimeout）at System.Net.Mail.SmtpConnection.GetConnection（的ServicePoint servicePoint）at System.Net.Mail.SmtpTransport.GetConnection（ServicePoint servicePoint）在System.Net.Mail.SmtpClient.GetConnection（）处 System.Net.Mail.SmtpClient.Send（MailMessage消息）---内部结束异常堆栈跟踪--- at System.Net.Mail.SmtpClient.Send（MailMessage消息）at Form1.Mailing（）in C：\的Inetpub \虚拟主机\ pay2school.net \的httpdocs \ IPTest \管理员\ Form1.aspx.cs：线 139

我依赖此错误消失。 :( 我用smtpout.secureserver.net更改了我的SMTP服务器但没有工作。请帮帮我。提前谢谢。

Answer 1

EnableSsl应该是真的。如果您需要超时，则应在发送电子邮件之前设置其属性，尝试按此调整

SmtpClient smtpClient = new SmtpClient();
smtpClient.Host = "relay-hosting.secureserver.net";
smtpClient.Port = 465;
smtpClient.EnableSsl = true;
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = 
          new NetworkCredential("mailadress@server.net", "Password");

...
smtpClient.Timeout = 10000;
smtpClient.Send(message);

当我说我以前的C＃工作代码（使用Godaddy服务器发送电子邮件）不再发送电子邮件时，我遇到了同样的问题。所以我花了5个小时来找到实际问题

问题是Godaddy 更改了服务器上的设置。因此，您无法使用以下方式发送电子邮件：

＆＃34; smtpout.secureserver.net＆＃34;主机。
本地主机（本地系统）。

我通过做两件事来解决这个问题：

使用SmtpClient主机作为＆＃34; relay-hosting.secureserver.net＆＃34;。
将我的网页放在我的Godaddy共享服务器上（由于Godaddy添加了安全性，localhost仍然无法发送smtp电子邮件）。

这是我这边的正确的工作代码：

MailMessage mailMessage = new MailMessage();
mailMessage.From = new MailAddress("test@yourdomain.com");
mailMessage.To.Add(new MailAddress("senderemail@gmail.com"));

mailMessage.Subject = "hello";
mailMessage.IsBodyHtml = true;
mailMessage.Body = "hello how are you";

SmtpClient client = new SmtpClient();
client.Credentials = new System.Net.NetworkCredential("test@yourdomain.com", "yourpassword");
client.Host = "relay-hosting.secureserver.net";
client.Send(mailMessage);

在上面的代码中，看看我添加了主机：

client.Host = "relay-hosting.secureserver.net";

邮件将在25到30秒的时间内到达。如果您仍然无法找到该电子邮件，请检查您的垃圾邮件文件夹。

在撰写此答案时，我测试了我的代码并找到了发送电子邮件到我的Gmail收件箱。请参见下图作为证明：

检查以下代码。您必须更改client.Host = "smtpout.secureserver.net."

MailMessage msg = new MailMessage(txtemail.Text, "shopover@vibrantinfosystems.com");
msg.Subject = "Contact Us";
string body = "Name: " + txtname.Text.Trim() + "";
body += "<br />Email:" + txtemail.Text + "";
body += "<br /><br /> Subject :" + txtsubject.Text + "";
body += "<br /><br />Message : " + txtmessage.Text + "";
msg.Body = body;

msg.IsBodyHtml = true;

SmtpClient client = new SmtpClient();
client.Host = "smtpout.secureserver.net.";

client.Send(msg);
client.Timeout = 10000;
ClientScript.RegisterStartupScript(GetType(), "alert", "alert('Mail Sent Successfully!!');", true);
