How do I avoid a delay when sending email from my application?

Question

I have a small console application. It checks a few settings, makes some decisions, and sends an email. The problem is the email doesn\'t actually get sent until my application

Answer 1

Create a new MailMessage and send it with SmtpClient. It will send immediately. I will add an example.

EDIT: Populate the variables host, port with the smtp ser ver name and port number.

using (var mailer = new SmtpClient(host, port))
{
    using (var message = new MailMessage(sender, recipient, subject, body) { IsBodyHtml = false })
    {
        mailer.UseDefaultCredentials = false;
        mailer.Credentials = new NetworkCredential(user, pass);
        mailer.EnableSsl = useSSL;
        mailer.Timeout = Timeout;
        mailer.Send(message);

    }
}

If you still experience a delay, then the delay will be at the mail server.
