Send email using my SMTP Server

Hi, I tried to send an email using my SMTP Server to any gmail account, but couldn’t. I’m using this code

            MailMessage mailMessage = new MailMessage();
            mailMessage.From = new MailAddress("[e-mail]");
            mailMessage.To.Add("[e-mail]");
            mailMessage.Subject = "subject";

            mailMessage.Body = "body";
            mailMessage.IsBodyHtml = true;

            SmtpClient smtpClient = new SmtpClient("localhost", 25);
            smtpClient.UseDefaultCredentials = true;
            smtpClient.Send(mailMessage);

The listener is receiving the message and is handeling it.

But unfortunately the gmail account is not receiving the message. Did I use it wrongly?

All this library does is receive email. It doesn’t onforward it for you. You can extend this library to do that for you.
