[Dovecot] Cannot delete subfolder in public folder

[Karsten Becker]

Hi there,

I have the problem that I'm unable to delete a subfolder (again) I
created within a public folder.

I've already read about configuring Thunderbird to delete immediately -
which I did. But it still doesn't work.

I delete -> the folder is gone -> I get a TB error message saying "The
folder doesn't exist" -> after restarting TB the folders appear again.
Maybe someone has a hint. My tip is that I may have a wrong
understanding of the ACL mechanism...  :-(

Regards from Berlin/Germany

Here's the filesystem structure in /srv/vmail:

> root at mail01.compdmz.local:/srv/vmail# ls -l public_folders/test01/
> total 20
> drwxr-xr-x 5 vmail vmail 4096 2011-08-23 23:50 aaa

Here's the content of dovecot-acl (there are another ones in subfolder
aaa with the same content, inherited during creation):
