Email Notifications in Default Client Event (Blackpearl 4.6)

I just installed K2 Blackpearl 4.6 and am currently experiencing an issue with email notifications in the default client event of my workflow project.  What's happening is that the email notification never gets sent.  I know there have been posts written about this, but I've not been able to find a solution.


Before I installed 4.6, I had K2 Blackpearl 4.5 installed, and I never had this issue in 4.5.  Here's the error I'm seeing in the event viewer log:


"744891","2012-04-20 13:51:44","Error","MessageBus","61007","SendMessageException","MessageBusRuntime","61007 Permanent failure sending message Request Approval: System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it xx.xx.xx.xx:xxx

I ensured that the smtpserver value in SourceCode.EventBus.EventAssemblies.dll has the correct value.


Any ideas??

By the looks it seems that your notification is trying to use SSL ports to send the notification mail instead of port 25. Download the Connection string editor tool. Place it in the HostServerin folder and run it. Change the SMTP TLS settings to NONE if they are BOOTTLS with port 25.

Let me know if this helps.

One more thing, remember to create a backup of the K2HostServer.config.

I downloaded the tool to K2 blackpearlHost ServerBin.  However, when I run it, I get an unhandled exception error message, with the following description:


Failed to decrypt using provider 'K2ConfigurationKey'.  Error message from the provider: The RSA key container could not be opened. (D:Program Files (x86)K2 blackpearlHostServerBinK2HostServer.exe.config line 82).

 Ok so you copied the exe to the HostServerBin dir and did you run it as the K2 Service account?

Yes, I had copied the exe to the HostServerBin dir.  I was able to get the app to launch once I ran it as the K2 Service Account.  


The SMTP TLS settings were BOOTTTLS, so I changed them to none.  I did this for both SourceCode.Net.Mail.SmtpConnection:system@k2.local and SourceCode.Net.Mail.SmtpConnection.   I tried initiating the process again, but am still getting the same error message.

Vernon -


Never mind, I got it to work.  The host name in the settings was incorrect.  Once I corrected it, the notification got sent.


Thanks again for your help.

Vernon,


Once I make the changes using the ConnectionStringEditor tool, is there anything else that needs done before the changes become valid?  I made the changes suggested (changed from BootTLS to None), but we're still not receiving email on port 25.


Thanks,

you have to stop the K2Service and start it again for the connection string to be encoded again. if it still doesnt work, please check the K2ServerLogs, maybe you have some other issue, provide details on the error thrown in the logs.

Hi Vernon,


 


I have a similar problem, I also have copied the Connectionstring editor to Hostserver bin and have tried opening it with the K2 Service Account but get the following message "Failed to decrypt using provider 'K2ConfigurationKey'. Error message from the provider: Bad Data"
