dovecot - Oct 2010 - virtual plugin broken ? dovecot 2.0.6

Hi Timo,
looks like virtual plugin is broken now with my setup dovecot 2.0.6
cant say to which version it stopped working ( didnt tested it trough
all ) but has worked

i see nothing special in log why it stopped working

it should show unseen mail i.e in folder Junk too
with pop3 clients, but only shows new inbox mails

after all i am confused what using better

pop3_uidl_format = %08Xu%08Xv ( most compatible )
or
pop3_uidl_format = %g ( better with virtual )

pop3_reuse_xuidl = ? what ist the most compatible/konservative setting
with maildir on a cluster filesystem

pop3_save_uidl = ? what ist the most compatible/konservative setting
with maildir on a cluster filesystem

%g is always the best value, except with mbox because it doesn't have
true GUIDs. Of course, if you change it now the pop3 clients will
redownload all mails.

This is useful only if you converted from another POP3 server to
Dovecot. Keep it "no".

This can be useful if you're changing pop3_uidl_format setting. First
set this to "yes", then make sure all users have logged in with POP3,
and then it's safe to change pop3_uidl_format because the old UIDLs have
been permanently saved to dovecot-uidlist file.

I don't think you need the INBOX lines above, since RealMails/* should
match them already.

This no longer works like this with v2.0. Change them to e.g.:

AS namespace_1_inbox -> AS 'namespace/default/inbox'
AS namespace_2_inbox -> AS 'namespace/virtual/inbox'

Then give those same names to your namespaces:

namespace default {
