I get an error sending email when using your sample c# code. http://www.bakushopping.com/webform1.aspx Error: System.Net.WebException: The remote name could not be resolved: 'mail.bakushopping.com' at System.Net.ServicePoint.GetConnection(PooledStream PooledStream, Object owner, Boolean async, IPAddress& address, Socket& abortSocket, Socket& abortSocket6, Int32 timeout) at System.Net.PooledStream.Activate(Object owningObject, Boolean async, Int32 timeout, 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(String host, Int32 port) at System.Net.Mail.SmtpTransport.GetConnection(String host, Int32 port) at System.Net.Mail.SmtpClient.GetConnection() at System.Net.Mail.SmtpClient.Send(MailMessage message) --------------------------------- <%@ Import Namespace="System.Net.Mail" %> <script language="C#" runat="server"> protected void Page_Load(object sender, EventArgs e) { //create the mail message MailMessage mail = new MailMessage(); //set the addresses mail.From = new MailAddress("[email protected]"); mail.To.Add("[email protected]"); //set the content mail.Subject = "This is an email"; mail.Body = "This is from system.net.mail using C sharp with smtp authentication."; //send the message SmtpClient smtp = new SmtpClient("mail.bakushopping.com"); NetworkCredential Credentials = new NetworkCredential("[email protected]", "******"); smtp.Credentials = Credentials; try { smtp.Send(mail); lblMessage.Text = "Mail Sent"; } catch (Exception ex) { lblMessage.Text = ex.InnerException.ToString(); } } </script> <html> <body> <form id="Form1" runat="server"> <asp:Label id="lblMessage" runat="server"></asp:Label> </form> </body> </html>
fixed Found the problem. I updated my DNS entries a few hours ago, and it appears the changes to smpt server is not yet available. I did a nslookup on my smpt server to get the ip, and then changed my mail server name to the IP, and then everything worked fine.
