SMTP failure

[Chubbly Geezer]

Hi
I am using the following code to send an email from within my program:-

MailMessage theMailMessage = new MailMessage("fr**@email.com", "[e-mail]");
theMailMessage.Body = "body email message here";
theMailMessage.Attachments.Add(new Attachment("pathToEmailAttachment"));
theMailMessage.Subject = "Subject here";

SmtpClient theClient = new SmtpClient("IP.Address.Of.Smtp");
theClient.UseDefaultCredentials = false;
System.Net.NetworkCredential theCredential = new System.Net.NetworkCredential("us**@name.com", "password");
theClient.Credentials = theCredential;
theClient.Send(theMailMessage);

however I keep getting the following error:-

System.Net.Mail.SmtpException: Failure sending mail. ---System.Net.WebException: Unable to connect to the remote server ---System.Net.Sockets.SocketException: An established connection was aborted by the software in your host machine

If you go there, you can download the code, and experiment with the different authentication modes.
