didnt tried that, but i have tested horde/imp and mulberry as clients
and they dont produce such error in the log
normally i would say it some kind of TB special

that would be nice cause listescape might be needed with usernames
having dot in their names

hm...? dont know what to say, it not urgent for me
as long as it only produces log entries and all other stuff
i need works, perhaps i should setup a fresh install in vmware
cause all the testing may brake something, and see if it apears again

for sure out of quota should be enough, but you know how users are
i see the question rising why a quota from shared folders cant be seen
it looks imcomplete, but if it would uprise security holes
forget it, or code it later , there is much more to do
which is more importend.
Its great to see shared folders and imap acl working in dovecot
cause your now going to be alternative to cyrus, this is what i searched
ever
