Unable to connect to remote server

I have a C# program that runs on my laptop and send an email, using my remote website to relay the email. But when I run the same program from a Virtual Private Server of mine, I get the error: Unable to Connect to Remote Server.

Dos anyone have any idea about what could be the problem? I could include the source code, but suspect the problem lies in the configuration or environment, versus the code.

Any idea of what to check?

Thanks,

Here is the code:

private static void SendCompletedCallback(object sender, AsyncCompletedEventArgs e)
{
// Get the unique identifier for this asynchronous operation.
MailMessage eMailMessage = (MailMessage)e.UserState;

if (e.Cancelled)
{
//Console.WriteLine("[{0}] Send canceled.", token);
}
if (e.Error != null)
{
//Console.WriteLine("[{0}] {1}", token, e.Error.ToString());
}
else
{
string emailAddress = (string)eMailMessage.To[0].Address;
eMailMessage.Dispose();
}
}

public void Send()
{
// Command line argument must the the SMTP host.
SmtpClient client = new SmtpClient(Handles.SMTPServer);

NetworkCredential nc = new NetworkCredential(Handles.Username, Handles.Password);
client.UseDefaultCredentials = false;
client.Credentials = nc;

// Specify the e-mail sender.
// Create a mailing address that includes a UTF8 character
// in the display name.
MailAddress from = new MailAddress(handles.FromEmail, handles.FromFirstName + " " + handles.FromLastName, System.Text.Encoding.UTF8);

// Set destinations for the e-mail message.
MailAddress to = new MailAddress(contact.EmailAddress);

// Specify the message content.
MailMessage message = new MailMessage(from, to);
message.Body = "";//"ApplicationPath=" + HttpContext.Current.Request.ApplicationPath;

// Include some non-ASCII characters in body and subject.
message.Body += Environment.NewLine;
message.BodyEncoding = System.Text.Encoding.UTF8;
message.Subject = "test message from " + handles.Preferences.MachineName;
message.SubjectEncoding = System.Text.Encoding.UTF8;

// Set the method that is called back when the send operation ends.
client.SendCompleted += new SendCompletedEventHandler(SendCompletedCallback);

// The userState can be any object that allows your callback
// method to identify this send operation.
// For this example, the userToken is a string constant.
//Object userState = this;
Object userState = message;
client.SendAsync(message, userState);
