Nasledujúci kód môžeme použiť aj pre iný SMTP server napr. smtp.azet.sk a port 25 (standardný port pre smtp).

Kód v C# :

using System;
using System.Windows.Forms;
using System.Net.Mail;
namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                MailMessage mail = new MailMessage();
                SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
                //nastav emailovu adresu odosielatela
                mail.From = new MailAddress("your_email_address");
                //nastav emailovu adresu prijimatela
                mail.To.Add("to_address");
                mail.Subject = "Projectik.eu";
                mail.Body = "Text.Ahoj.Hello.Nazdarek";
                //port gmail je 587,standardne pre ine smtp je port 25
                SmtpServer.Port = 587;
                SmtpServer.Credentials = new System.Net.NetworkCredential("username(a)gmail.com", "password");
                SmtpServer.EnableSsl = true;
                SmtpServer.Send(mail);
                MessageBox.Show("mail Send");
            }
            catch (Exception ex)
            {
