Hi list, We're running a ~100.000 users free webmail service, based on cyrus and ldap. Recently, some of our users started complaining that they can't see their subfolders anymore. I found the .sub files and also found this from the doc/server-design file: * User directory: The subdirectory "user" under the configuration directory contains files with per-user information. For each user "USER" with an INBOX, it may contain the file "USER.sub". The file contains a list of the user's subscribed mailboxes. Most of the .sub files I see are empty (zero lenght), altough _all_ of our users have sent-mail subfolder. I found some .sub files that only contained user.username line, and some that looked like what I would expect (user.username, user.username.sent-mail, user.username.somesubfolder). Of those that were complaining, I found that some didn't have .sub file and some have them, both empty and with a some subfolders. So I'm a bit confused here ... Is anyone willing to explain this stuff in more detail than there is in server-design doc file? Or at least suggest me which source files to dig through to find out how is all that supposed to work? Or, better yet, suggest me a way to fix those users' mailboxes? We're using cyrus 2.0.14. -- Jure Pecar
