Hello,

I have my mailserver (exim4) and imap-server (courier-imap) settings stored in a database for easy maintenance. This setup works fine, but I must prevent users from renaming shared folders, otherwise the maildir name gets changed and exim can't deliver the messages.

The solution I now have is to use an acl without 'x' on my non-mutable folder and with 'x' in subsequent folders.

Non-mutable:

owner aceilrstw anyone ceilrstw

Mutable:

owner aceilrstwx anyone ceilrstwx

#shared myfolder (non-mutable) test (mutable)

The drawback is that I can't (re)move any mutable folders ... according to Thunderbird the mailserver responds with that it cannot move folders to a different account (trash). Moving it to a different folder under #shared is also not possible.

Is there a workaround for this kind of problem?

An other solution, more user friendly, would be if courier-imap would call (hook) a script with params when a foldername was changed. The script could adapt the database setting accordingly.
