After upgrading to the latest version (R2), the system has started to deleted automatically anything in the trash folder after about 3 seconds. If I delete a mail item, there appears a (1) against the trash folder for a couple of seconds, which then disappears. If I go into the folder, it is now empty. This happens both from the web interface and the latest client. It has just started happening, and a server restart has not cured the problem. Nothing has been changed on the settings (delete trash after 7 days), and the date and time are correct.

Anyone got any ideas on how the solve this frustrating problem.
