I am testing the .NET SMTP component out against a couple of different servers. Some of the servers require SSL...others do not. I am able to connect, authenticate, and send email against the servers that do not require SSL.

However, when I attempt to send a message to a server using SSL...I receive the MailBeeSslWin32Exception.

Here is how I am setting the SSL mode of the SMTP server:

server = New SmtpServer(txtSMTPServer.Text, txtSMTPUsername.Text, txtSMTPPassword.Text)
             If chkUseSSL.Checked Then
                server.SslMode = Security.SslStartupMode.OnConnect
             End If
             mailer.SmtpServers.Add(server)

What am I missing? I've tried this against a couple of servers like gmail, our exchange server, etc.

Thanks,
Mike

Accordingly MailBeeSslWin32Exception Class description, you made an attempt to connect to a wrong port. You should either connect to SSL port (such as 465 for S/SMTP) or tell MailBee to connect to a regular port and then switch to SSL mode using STARTTLS command.
Code:

' Connect to SSL port
If chkUseSSL.Checked Then
  server.Port = 465
End If

or
Code:

' SSL over regular port (STARTTLS)
If chkUseSSL.Checked Then
  server.SslMode = Security.SslStartupMode.UseStartTls
End If

Alex

Alex,

I am setting the port to 465 in my code (not the snippet I provided). Previously, I was using the UseStartTls mode but was getting messages that the protocol was not supported. So...I went with the approach that I outlined above.

Any other ideas why this would be failing?

Thanks,
Mike

Alex,

My bad, the port was not getting set correctly after I set the SSL mode. Once I did this, it worked fine.

Thanks for the quick response.

Mike

Could you please set UseStartTls mode back, revert to default port (25), enable logging SMTP session into a file, then reproduce the problem by making an attempt to connect to smtp.gmail.com, and then send us the log to support@afterlogic.com? You can enable logging as follows:
Code:

smtp.Log.Enabled = True
smtp.Log.Filename = "C:\log.txt"

Regards,
Alex
