If you have an issue with Xpunge, please send me an email using the "Support E-mail" link on Xpunge's addons.thunderbird.net page, and I will do my best to help you troubleshoot.
ATTENTION: Compacting folders means that all the messages you have previously deleted from those folders are permanently deleted from the hard disk and cannot be retrieved again.
ATTENTION: Be careful when you use the functionality for emptying the junk folders. It is not the same as emptying the trash folder, in the sense that messages are deleted on purpose, whereas your spam filter may put useful (non-spam) emails in the junk folder, so emptying this folder will cause you to lose those emails. Xpunge has all the junk features turned off by default to avoid accidents. Please enable and use the junk functionality at your own risk.
ATTENTION: When you select to empty the Junk of an account, all the folders of that account that are known to Thunderbird to be "junk" folders will be emptied. For example, if you set up a Gmail IMAP account, where the junk folder is called "Spam", and you also change the settings of that account in Thunderbird to move new junk messages to a folder called "Junk", both folders will be emptied if you enable emptying the Junk for that account in Xpunge.
The buttons offered by Xpunge do not appear on the various Thunderbird toolbars by default, you will have to add them yourself. Also, the button icons contained in the packages offered here are of size 16x16 (small) and 24x24 (large) pixels. If these icons are smaller than what your current theme is using, you can find a version with slightly larger icons on Xpunge's homepage. However, if you install Xpunge from my website, keep in mind that you will no longer be able to automatically update it. So checking for an available update of Xpunge from the addons page in Thunderbird will no longer report any updates. You will have to periodically monitor my website or this page here yourselves to see if any updates are available and then manually download and install the corresponding xpi file from my website.
