No, Auto expunge works fine with POP3 and IMAP accounts without (synchronizing). But when you enable synchronizing (option "Select this folder for offline use") it will no longer correct: Server folders will be compacted but the appropriate offline folders will not be compacted until I press File\Compact Folders.

aside from the issue of different sizes, I don't think there's an integrity or any practical problem here. 

invalid?

First problem i see here if you receive huge amount of email everyday and running low on space on your hdd. But in this case you shouldn't using synchronizing in first place because it caches everything and eat up everything else.
Second problem is security concerns.

We have a bug report for that iirc.

wadim, see http://support.mozillamessaging.com/en-US/kb/imap-synchronization
- If you no longer see the problem, please set status to RESOLVED, and set resolution to WORKSFORME.

otherwise, we can probably mark this as a duplicate of some other bug.


> Second problem is security concerns.

wadim, please file a seperate bug if you still see this issue

The bug is still here (thunderbird 10.0.2).
The option 'Compact folders when it will save over N Mb' doesn't work with IMAP synchronizing.

which files are  not being compacted - the files on the server, or the files on the PC?
