c# - SMTP Gmail timing out

Question

Not sure why this is happening. Every where I've search tells me that i'm doing this right. But every time I try and send the mail, it times out on the smtpserver.Send(mail)

private void emailReport(string email_address,int begDatabaseCount, int endDatabaseCount)
        {
            SmtpClient smtpserver = new SmtpClient();
            MailMessage mail = new MailMessage();
            smtpserver.EnableSsl = true;
            smtpserver.Port = 465;
            smtpserver.Host = "smtp.gmail.com";           
            smtpserver.Credentials = new NetworkCredential("mtaylor@atr.com", "password");
            smtpserver.UseDefaultCredentials = false;
            mail = new MailMessage();
            mail.From = new System.Net.Mail.MailAddress("mtaylor@atr.com", "ATR Reports");
            mail.To.Add(email_address);
            mail.Subject = "FNAS Report - " + DateTime.Now;
            mail.Body += "<u><b>FNAS Report for " + DateTime.Now + "</u></b>" + "
 
";
            mail.Body += "Beginning Database Count - " + begDatabaseCount + "
" + "
";
            mail.Body += "End Database Count - " + endDatabaseCount + "
" + "
";
            mail.Body += "<b>Total Imported Orders = " + (endDatabaseCount - begDatabaseCount) + "<b>" + "
" + "
";
            mail.IsBodyHtml = true;

            smtpserver.Send(mail);
        }

Port 465 = Time Out after 1 minute

Port 587 = "The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required. "

Answer 1

As @kostyan said, the right port is 587, but to authenticate you need to allow access from less secure apps in your gmail account. Try it here

It worked for me, hope it helps..
