Introduction

Recently I involved in .NET project, where last developer that worked in project has used a non native class to send mail. Well, I have problems with used solution. The used component doesn't work well on windows 2k3. This problem was solved using SMTP object form .NET 2.0. It's very simple to use.

Using the code

There are one basic class myMail. This class has a method to setting SMTP and sends mail.

static class myMail
    {
        public static string sendMail(string to, string cc, string bcc, string subj, string msg)
        {
            SmtpClient smtp = new SmtpClient();
            MailMessage message = new MailMessage();
            string[] myCC;
            string [] myBCC;
           
            myCC = cc.Split (';');
            myBCC = bcc.Split (';');
            try
            {
                foreach (string ccCopy in myCC)
                {
                    message.CC.Add(new MailAddress(ccCopy));
                }
                foreach (string bccHide in myBCC)
                {
                    message.Bcc.Add(new MailAddress(bccHide));
                }
                message.To.Add(new MailAddress(to));
                message.Subject = subj;
                message.Body = msg;
                smtp.Host = "teste";  // hostname smtpserver
                smtp.Port = 25;       // smtp server port
                message.From = new MailAddress("<a href="mailto:paulo.passos@xxxxxxxxxx.com.br">paulo.passos@xxxxxxxxxx.com.br</a>");
                smtp.Send(message);
            }
            catch (SmtpException E)
            {
                return "Mail send failed with message: " + E.Message;
            }
            return "Mail was send";
        }
    }
    // sending mail from project
    //
    private void btnSend_Click(object sender, EventArgs e)
    {
        MessageBox.Show (myMail.sendMail(txtTO.Text , txtCC.Text , txtBCC.Text , txtSubject.Text , rtMsg.Text));
    }
