[cyrus-imapd] unexpunge folder problem

[Marco]

Hi,
I have a problem using unexpunge. It works as expected recovering  
INBOX messages, but if I delete an entire folder, I can't see it on  
'unexpunge -l user/<uid>@<domain>'. I also tried 'unexpunge -l  
user/<uid>/<folder>@<domain>', where <folder> is the folder deleted  
that I want unexpunge.

Same problem if I delete the entire mailbox (with dm  
user/<uid>@<domain> from cyradm). If I recreate the user I can't  
recover it with unexpunge, even if cyradm 'lm' command show  
DELETED/user/<uid>@<domain>.

Could you help me?

This is my conf (Invoca RPM build with delete_mode:delayed and  
expunge_mode:delayed):
