Hi, we are using critsend's SMTP servers for our newsletters. Using the standard
.NET SmtpClient with System.Net.NetworkCredential works, but we can't make it
work with MailBee's SmtpServer.

The following code fails because the server answers "The server does not support
STARTTLS (STLS for POP3) command.":

SmtpServer smtpServer = new SmtpServer("smtp.critsend.com");
smtpServer.Port = 587;

smtpServer.AccountName = "MY NAME";
smtpServer.Password = "MY PASSWORD";

Smtp.LicenseKey = "MY KEY";
Smtp smtp = new Smtp();
smtp.SmtpServers.Add(smtpServer);
MailMessage mailMessage = new MailMessage();
mailMessage.To.Add("MY EMAIL");
mailMessage.Subject = "Test";
mailMessage.From.Email = "MY EMAIL";
smtp.Message = mailMessage;
smtp.Send();

Setting smtpServer.SslMode = SslStartupMode.Manual doesn't help. How can I turn
off StartTLS?

We are using MailBee.NET.5.5.2.138.

Any help is greatly appreciated.

Does the following help?

Code:

smtpServer.SslMode = SslStartupMode.OnConnect;

Thanks for the quick reply, but no, it says now:

System.IO.IOException: The handshake failed due to an unexpected packet format.

And what about UseStartTlsIfSupported value? Also, make sure you're using the latest version of the DLL.
