Testing mail settings, not sending a mail, missing authentication?!

[LHT]

Ok, don't ask why, but on Windows Server 2016 as client there is even no authentication needed that's why it works.

[LHT]

Hey guys,

me again. Now I have installed BestSync 17.0.0.5 on the productive Windows Server 2016 system. Sadly it does not work.

The authentication string BestSync is sending always is longer than mine with the working test program.

May an option which should be settable in the option UI?
I cannot do changes in the SMTP server!

Here is the little code snippet of my test program written in C#:
MailMessage mail = new MailMessage();
mail.From = new MailAddress(
"service@address.de",
"service@address.de"
);
mail.To.Add(new MailAddress(
"my@address.de",
"My name")
);
mail.Subject = "Test-Subject";
mail.Body = "<b>Test Body</b>";
mail.IsBodyHtml = true;
SmtpClient mailClient = new SmtpClient(this.textBoxHost.Text);
NetworkCredential credentials = new NetworkCredential(
this.textBoxBenutzer.Text,
this.textBoxPasswort.Text
);
mailClient.Credentials = credentials;
mailClient.Send(mail);
