I move from Thunderbird 52 to 60, to make trials before to install it to all our users. My thunderbird manage 3 different e-mail account, of our local webmail service, gmail and hotmail accounts. Due to the large amount of email I receive, and the space limit in our mailserver, I need to move the mail to local folder using the filters. This worked very very well in last 10 years. Now, using the last Thunderbird version 60 I found a very boring bug, or at leasts I suppose is a bug. What happen? When I write a new message time by time Thunderbird it write a copy in the draft folder in the mailserver folder... or better it should write there the draft, in practice the draft copy is going to the folder decided by the filter. So I am finding in a local folder all my draft together with the received email, and so I need to erase.. erase... erase... Of course I checked the account settings, and all it look ok. What can I do to solve the trouble??
