I can send SMS using the mailbee, using web interface, But if I use the same code in an console application , when sending an email I'm receiving the below error.

This Win32 error means "The client and server cannot communicate, because they do not possess a common algorithm.". The error occurs somewhere in Windows so I can only guess what it could mean. Perhaps, the server does not support some SSL algorithm.

Please enable log with Smtp.Log property (or which class you're using to send emails which are then treated as SMS messages by the third party). The log may shed more light on this.

There is also SmtpServer.SslProtocol property which you can from the default Auto value, e.g. Smtp.SmtpServers[0].SslProtocol = SecurityProtocol.Ssl3 but without the log file I can't be sure.

Alex

That's a really outdated version of the product, check if you're getting the same problem using current version of MailBee.NET Objects available for download here.

Hi Igor,

It is taking 2 to 3 minutes to send one SMS. It is very slow in the server.

In the log file it stops recording when it reaches
"[14:36:03.59] [RECV] 220 2.0.0 SMTP server ready\r\n"

Then it waited for 2 minutes then started to send one SMS.

[14:38:19.44] [INFO] Message successfully submitted to SMTP server.
[14:38:19.44] [SEND] QUIT\r\n
[14:38:19.46] [RECV] 221 2.0.0 Service closing transmission channel\r\n
[14:38:19.46] [INFO] Will disconnect from host "send.nhs.net".
[14:38:19.46] [INFO] Disconnected from host

Thanks,
Assal

What's in between? Looks like you omitted many commands in between.

Indeed, the log shows the delay over 2 minutes between these two lines:

Code:
[14:36:03.59] [RECV] 220 2.0.0 SMTP server ready\r\n
[14:38:18.88] [INFO] Will send Hello command (HELO or EHLO).


but it doesn't look like a delay on server's end, more like something happening on the application level. Please recheck if your application is doing anything between enabling STARTTLS and sending HELO; are you using just the Send method, or the application performs explicit connect to the server as well?

If you provide us with a self-contained sample which allows for reproducing the problem, we could look into this for you.

Looks like there is a problem with SSL handshake. The server is very slow when establishing SSL connection. Perhaps, that the reason why old version of MailBee returned this error (there was a timeout during SSL negotiation, some data received only in part, and so on).

Please provide the real server name, we'll check if it's indeed slow on SSL. You can send this to Helpdesk.

Alex

Hi Alex,

I've sent the server name to help desk.

From my PC it takes 2-3 seconds to send a SMS.

Only If I send it from my test server it takes 2-3 minutes to send a SMS. This test server is a Virtual Machine , OS is Windows Server 2008.Does it make any difference?

Thanks,
Assal

Never heard of such slowdown of SSL negotiation so I can't say why it happens. You can try to play with different settings of SslProtocol property in SmtpServer class (that instance you're adding to Smtp.SmtpServers collection). Usually, it doesn't make any difference and the default Auto setting is fine. But maybe it will be different in your case.

Alex
