Mailbox rights

[Anders Norrbring]

I have a rights problem it seems.. I run Cyrus IMAP 2.3.8 and have a
common mailbox for all users that should not be changed or deleted.
However, the mails in it should be free to delete for the user.

So, that box (f.x. user.anders.common) is set to lrswiptea for the user.
Seems correct as I understand it... However, the users cannot delete the
mails that comes to that box.
Am I on the wrong track?

Anders.
