If you happen to run Courier IMAP server that comes with cPanel, then you are probably experiencing a rather unpleasant feature . By default, Courier will regularly delete every single email from trash folder that is more than 7 days old.
Considering that most people use IMAP protocol to keep their messages safe and always available on the server, this default option can cause a lot of frustration. Luckily, fixing this issue is rather easy and quick (it takes less than a minute).
