My code to solve this problem:

{   
    //This list can be a parameter of metothd
    List lst = new List();

    lst.Add(new MailAddress("mouse@xxxx.com"));
    lst.Add(new MailAddress("duck@xxxx.com"));
    lst.Add(new MailAddress("goose@xxxx.com"));
    lst.Add(new MailAddress("wolf@xxxx.com"));


    try
    {


        MailMessage objeto_mail = new MailMessage();
        SmtpClient client = new SmtpClient();
        client.Port = 25;
        client.Host = "10.15.130.28"; //or SMTP name
        client.Timeout = 10000;
        client.DeliveryMethod = SmtpDeliveryMethod.Network;
        client.UseDefaultCredentials = false;
        client.Credentials = new System.Net.NetworkCredential("from@email.com", "password");
        objeto_mail.From = new MailAddress("from@email.com");

        //add each email adress
        foreach (MailAddress m in lst)
        {
            objeto_mail.To.Add(m);
        }


        objeto_mail.Subject = "Sending mail test";
        objeto_mail.Body = "Functional test for automatic mail :-)";
        client.Send(objeto_mail);


    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}
