Hi,

I'm one step away from replacing a 7 years old qmail/uw-imapd setup with some state of the art soft- and hardware. We got migration scripts and test almost done - just one thing that keeps failing:

The autocreate plugin is supposed to subscribe new users to different mailboxes, one of them being in namespace "Public." - this subscription to "Public.announcements" fails.

Below is a dovecot -n - and no, there are no error messages in the logs.

Any hints are really appreciated.

BTW: If anybody is interested, I could provide load and usage statistics of our old and new software once step 1 of our migration (new hardware is step 2) is done. Only ~1000 users, but still...
