Hi Timo,
Oh, right, that's because the subscriptions are in the private namespace. Hmm. I'll try to get this fixed soon, but if you want to get it working now you could use:
namespace public { prefix = shared. location = maildir:/var/mail/vmail/%d/shared:CONTROL=~/shared:INDEX=~/shared subscriptions = yes }
Then subscriptions will be handled directly in the public namespace, therefor all users would have the same folders subscribed, right?
That would cause permission problems, as not all users are allowed to see every folder.
Although there's also a bug related to that where LSUB "" % won't list "shared" and that breaks some clients. That's fixed in v1.2.6.
Such commands are actually performed and logged in the rawlog (e.g. 20091005-221025-26325.in), but I don't see any responses back to the client.
I'll upgrade to 1.2.6 and check if the problem still occurs.
