Wolfgang: I also observed this "TB redownloads either 30 or 50 messages" with the gmail account that Connor gave me, and I have one possible explanation. During the initial download with the debug version, I can see a number of cancelled downloads due to failures to acquire a folder lock here:
c:/tb/beta/src/mailnews/imap/src/nsAutoSyncState.cpp, line 643 After some period of time, there were additional attempts to download messages from folders that I thought were already done, and it is possible that those earlier failures were being downloaded. I have not fully confirmed that this is the cause, but it is a possible explanation. -- 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.
