Done that and now I see a lot of " Expunged message reappeared, giving a new 
UID (old uid=10753, file=...)" ugh :-/

I guess now imap clients will see these as new messages?

Also ": IMAP(bo): /var/lib/dovecot/control/xxx/.INBOX/dovecot-uidlist: 
Duplicate file entry at line..."

Weird, these are fresly created control files and now they contain duplicates.

Last question, what permissions are needed for /var/lib/dovecot/control/ if 
it's used as CONTROL= and users use different uid/gids? Right now I have 
a+rwx which doesn't look nice and root:root 660 also didn't make dovecot 
happy.
