asp email System.Net.Mail

Question

Using this code (System.Net.Mail):

SmtpClient client = new SmtpClient();
client.Send(MyMessage);

I get this error:

System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it 127.0.0.1:25

Web.config entries.

Working code.

    message.Body = body;
    SmtpMail.SmtpServer.Insert(0, "");
    SmtpMail.Send(message);
    // lblmsg.Text = "Message sent successfully";
    RegisterStartupScript("startupScript", "<script language=JavaScript>alert('Message sent successfully.');</script>");
    clear();
}


 <system.net>
    <mailSettings>
        <smtp deliveryMethod="Network">
        <network defaultCredentials="True" host="LocalHost" port="25" />
        </smtp>
    </mailSettings>
</system.net>

What is wrong?

Answer 1

Make sure your firewall is allowing the port 25. also SMTP service is configured and running in your local machine.

Answer 2

Maybe you are just not running an SMTP server on your localhost.

Answer 3

You probably haven't got an smtp server running. Try if dumping the files on disk works:

<mailSettings>
  <smtp deliveryMethod="SpecifiedPickupDirectory">
      <specifiedPickupDirectory pickupDirectoryLocation="c:\Temp\mail\"/>
   </smtp>
</mailSettings>

If this works, then try setting up a local mailserver and change the settings back to your current values.

Answer 4

If it worked correctly with the same machine before you moved away from the deprecated method then I would assume that the default configuration for the .NET send mail is different than the default configuration for the older one.

Perhaps try removing the delivery method entry in the webconfig and use the default method.

I've connected to exchange this way before and never specified anything besides a from address, a host, username, and password.
