邮件未从网络托管服务器发送

Question

我在我的网站上有联系表格。使用 GoDaddy 进行 Windows 托管。当我在本地主机中测试联系人时，它可以正常工作并发送邮件，但在托管时会出现异常。

System.Net.Mail.SmtpException：发送邮件失败。 ---> System.Net.WebException：无法连接到远程服务器 ---> System.Net.Sockets.SocketException：试图以访问权限 74.125.130.108:587 禁止的方式访问套接字在 System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) 在 System.Net.ServicePoint.ConnectSocketInternal (Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Exception& exception) --- 内部异常堆栈跟踪结束 --- 在 System.Net.PooledStream.Activate(Object owningObject 的 System.Net.ServicePoint.GetConnection(PooledStream PooledStream, Object owner, Boolean async, IPAddress& address, Socket& abortSocket, Socket& abortSocket6) , 布尔异步, GeneralAsyncDelegate asyncCallback) 在 System.Net.PooledStream.Activate(Object owningObject, GeneralAsyncDelegate asyncCallback) 在 System.Net.ConnectionPool.GetConnection(Object owningObject, GeneralAsyncDelegate e asyncCallback, Int32 creationTimeout) at System.Net.Mail.SmtpConnection.GetConnection(ServicePoint servicePoint) at System.Net.Mail.SmtpTransport.GetConnection(ServicePoint servicePoint) at System.Net.Mail.SmtpClient.GetConnection() at System.Net .Mail.SmtpClient.Send(MailMessage message) --- 内部异常堆栈跟踪结束 --- 在 System.Net.Mail.SmtpClient.Send(MailMessage message) 在 DynamicPage.sendInquiry_Click(Object sender, EventArgs e) 在 G： \PleskVhosts\brandstik.in\httpdocs\DynamicPage.aspx.vb:173 行

try {
    MailMessage mail = new MailMessage();
    SmtpClient SmtpServer = new SmtpClient();
    mail.To.Add("abc@gmail.com");
    mail.From = new MailAddress(inquiryEmail.Text);
    mail.Subject = "Quote Request For " + quoteID.Text;
    mail.Body = "New Quote request from customer<br /><br/>Customer Name - '" + inquiryName.Text + "' <br />Customer Email - '" + inquiryEmail.Text + "'<br />Customer Contact - '" + inquiryNumber.Text + "'<br />Comment - '" + inquiryMessage.Text + "'";
    mail.IsBodyHtml = true;
    SmtpServer.Port = 587;
    SmtpServer.Credentials = new System.Net.NetworkCredential("xyz@doamain.com", "1234567890");
    SmtpServer.Host = "smtp.gmail.com";
    SmtpServer.EnableSsl = true;
    SmtpServer.Send(mail);
    Response.Write("Sent");
} catch (Exception ex) {
    //Response.Write("<script language='javascript'>alert('Your SMTP Server needs to get configured to contact form work.');</script>")
    Response.Write(ex);
}

似乎他们不允许。您需要使用 GoDaddys 电子邮件中继服务器。在此处查看手册：https://www.godaddy.com/help/send-email-using-systemnetmail-19291
