at our place there are a couple of users, who are working on the same mailaccount via IMAP, configured in theirr mailclient Thunderbird.
Every now and then it happens, hopefully in error, that someone moves a complete folder with 12000 mails or creates a folder, which others don't see. They try again and again and finally i need to clean out four times the same folder in different places via omcontain.
Is there a possibility to deny creating and moving folders via IMAP, but leave the ability to move mails, e.g. archiving them?
btw.: Is it still true, that you shouldn't create new folders under system folders like the in- or outtray?
