Prevent a folder from being deleted?

[bb+lists.cyrus-info]

Hi,   I have a mail-folder where I in fact want all access to, but I want to prevent myself from deleting the folder (like with the INBOX folder – at least under Outlook I can’t accidently delete it.) In the man cyradm file I don’t see a right that I can exclude to make this happen. (At least, not as far as I understand it :-P) Is there any way of doing this? I’m using v1.6.24   Paul
