User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0 Build ID: 20160105164030 Steps to reproduce: Attached a certain image to a message Actual results: Probably the image got inside some code which alerts a spam control inside the SMTP server, which responds: 5.2.0 spam detected. I already made my ISP aware of the wrong spam control; what involves TB is that the message is copied in the Sent folder, as if it was sent correctly, while it's not! Expected results: TB should return to compose window and NOT copy the message to the Sent folder
