File To Mail - Error in sender CC

Hi All,

I am trying out a File to mail scenario following the Blog /people/michal.krawczyk2/blog/2005/03/07/mail-adapter-xi--how-to-implement-dynamic-mail-address

I am getting the following error in the File Sender Comm Channel :

Mail: error occurred: com.sap.aii.af.mp.module.ModuleException caused by: com.sap.aii.messaging.srt.BubbleException: Failed to call the endpoint [null "null"]; nested exception caused by: java.io.IOException: no sender address specified

I could also see the payload is empty in the Receiver Mail CC

Now can anybody help getting me the mail ...

Thanks in advance
