Is somebody with the bug willing to test whether it's related to the offline message size limit? Open the Mail Server properties for a folder showing this problem (right click on the mail server, select "Settings...", select the "Synchronization and Storage" settings, and check whether you have "Don't download messages larger than x KB" checked.
If you do have it checked, try un-checking it and see if the problem goes away - your client should download the large messages one more time and then stop. I've been looking at the log file on the Launchpad bug, and that log only shows us downloading each of the large messages once. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/1068921 Title: Mailbox grows endlessly, heavy traffic Status in Mozilla Thunderbird Mail and News: In Progress Status in “thunderbird” package in Ubuntu: Confirmed Bug description: Yesterday I noticed that my Internet connection keeps transferring a lot of data. After a while I checked with nethogs and discovered this was caused by Thunderbird. Today I got a warning that my HDD was near full. In this 2 days, the mailbox had grown to 20 GB, while in reality it should be around 1 GB (a fresh zipped backup has 600 MB). I removed the .thunderbird folder and configured my IMAP mailbox from scratch. The same happened again. I think this is not related to a somehow special configuration of my PC bcs my colleague discovered it's the same on his machine. Without checking, he wouldn't have noticed yet bcs of a much bigger HDD... We couldn't yet find out what exactly happens / which data is transferred again and again. I suspect it's related to the last thunderbird update.
