User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.103 Safari/537.36 Steps to reproduce: Send an e-mail, have a smtp-server working, the corresponding sent-folder is not reachable (server error or similar). Now a dialog pops up and tells "can not save Message to Sent-folder". Actual results: This dialog does not have any options that preserves the message for the user. We had to Cancel and the message was lost. Expected results: 1. The user should now, that the message was sent (this is not clear for not technical user) (maybe create an easy to view action log) 2. There should be an option to save the message to a local folder in the dialog.
