I have a problem forwarding emails from one of my banks containing bank statements to my accountant. I have setup message filters and all is working good for one bank, but emails from another bank won't forward at all. As soon as I run Thunderbird in the morning, I get the blank forward email from that bank containing only subject with my accountant email fulfilled, but no body and no attachments. Then I have to close that window, and do it manually every morning. I click the received email from bank, than forward, put forward address from accountant and send. Since yesterday's update of Thunderbird, I cannot even forward email from this bank (inline). The email is totally blank, no body, no attachment. If I select to forward as an attachment (*.eml) than it is all OK. All other emails forward fine. The problem is only with this bank. Also I have noticed that the digital signature from this bank is not valid, so maybe this is what is creating the problem.
