Nevíte kde udělali soudruzi z NDR chybu???
Nějak mi to nefunguje
System.Net.Mail.MailMessage Message = new System.Net.Mail.MailMessage(new System.Net.Mail.MailAddress(this.TextBox2.Text, this.TextBox1.Text), new System.Net.Mail.MailAddress("st-osp@seznam.cz", "Stanislav Ospalý"));
Message.Subject = this.TextBox3.Text;
Message.Body = this.TextBox4.Text;
Message.IsBodyHtml = false;
System.Net.Mail.SmtpClient Smtp = new System.Net.Mail.SmtpClient("smtp.isp-net.cz", 25);
Smtp.Credentials = new System.Net.NetworkCredential("Username", "Password");
Smtp.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
Smtp.Send(Message);
