Description of problem: I have my email account configured to only mark messages as deleted in Thunderbird. When checking for new messages (though not every time), thunderbird compacts (ie expunges) the deleted messages from the inbox and other folders. Version-Release number of selected component (if applicable): thunderbird-3.0-2.3.beta2.fc11.i586 How reproducible: Thunderbird will compact folders at least once a day. However, it does not appear to compact every time it checks for new email. It is not clear what the interval is. Steps to Reproduce: 1. Configure Thunderbird to 'mark message deleted' (Account Settings -> Server Settings). Make sure 'Clean up Inbox on exit' is not checked. 2. Mark some messages as deleted. 3. Check for new email. Repeat until folders are compacted. Actual results: Thunderbird will compact folders despite configured not to do so. Expected results: I mark messages as deleted and, at some later point, instruct Thunderbird to compact folders. Additional info: This behavior does not exist in Fedora 10 and Thunderbird 2. I obtain the expected results with Thunderbird 2 (thunderbird-2.0.0.21-1.fc10.i386).
