How to detect Ssl Type

To detect Ssl Type AIM will firstly tries to detect if it is a TLS (Explicit) connection. If not, it will try to connect to server as a Ssl Server, if both fails it will return None as ssl type

public SslMode DetectSslType(string host, string tlsPort, string user, string pass){
    var mailer = new MimeMailer(host, tlsPort)
    {
            User = user,
            Password = pass,
            AuthenticationMode = AuthenticationType.Base64
    };
    mailer.SendCompleted += compEvent;
    return mailer.DetectSslMode();
}

private void compEvent(object sender, AsyncCompletedEventArgs e)
    if (e.UserState != null)
            Console.Out.WriteLine(e.UserState.ToString());
    if (e.Error != null)
    {
            MessageBox.Show(e.Error.Message, "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
    }
    else if (!e.Cancelled)
    {
            MessageBox.Show("Send successfull!", "Information", MessageBoxButtons.OK, MessageBoxIcon.Information);
