Hi - I think you mean compare the actual mail spool to the contents of (on Arch) /var/imap/user/d/djones.sub Yes, as far as I can tell the subscription file contains only valid mail folders; however, I did notice that one of the mail subfolders starts with a number: user.djones.Archives Staff.1Amy Smith Could this be causing the problem? One point of confusion. I've been using unixhierarchysep: yes ever since I started using 2.4.17, but the entries in user/username.sub are still listed using "." as the separator? What happens when a user has a "." in the mailbox folder name?
