I have tested thunderbird trunk now with two different Imap server. Thunderbird against Dovecot works as expected, emails are downloaded to local Imap folders and everything is fine.
Thunderbird against Zarafa downloads emails but when finished the local Imap folders are reset to a very small size, so emails are not kept. This causes thunderbird to download over and over again. I have started completely fresh with thunderbird trunk. Anything I can to help debugging? I.e. this issue is not fixed... I have also reported this issue in Zarafa forum, https://forums.zarafa.com/showthread.php?8211-A-few-users-with-IMAP-performance-issues-via-Thunderbird. -- 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/1074260 Title: Thunderbird heavy IMAP traffic downloading messages Status in Mozilla Thunderbird Mail and News: Fix Released Status in “thunderbird” package in Ubuntu: Confirmed Bug description: Thunderbird (as of version 16?) generates a lot of IMAP traffic, continually redownloading messages.
