You didn't add exec-and-wait, you replaced your entire interceptor stack with just the exec-and-wait interceptor.

I got the following Error message returned. Could someone help what is missing? I found examples about progressbar + fileupload, but what about waiting for sending emails, is there a online doc about this? Thanks a lot!
