SMTP Clients

[lxXTaCoXxl]

I'm trying to develop a class library that contains some of the code I don't like having to type into multiple applications. So I need help figuring out if my coding is right on this one? I don't have an SMTP server to test with.

public void Send(String client, Int32 port, String username, String password, String to, String from, String subject, String body)
        {
            SmtpClient mClient = new SmtpClient(client, port);
            mClient.Credentials = new NetworkCredential(username, password);
            MailMessage mMessage = new MailMessage();
            mMessage.To.Add( new MailAddress(to));
            mMessage.From = new MailAddress(from);
            mMessage.Subject = subject;
            mMessage.Body = body;

            try
            {
                mClient.Send(mMessage);
            }

            catch (Exception e)
            {
                MessageBox.Show("Could not send message do to the following reason: " + e.Message);
            }

All help is appreciated; this was coded by playing around in the .Net namespace; unfortunately I don't know if it's accurate.
