[Dovecot] problem with ~/mail/ namespace

[Tom Lieuallen]

We just changed from UW imap last night and one of our bigger problems 
right now is that the ~/mail/ compatibility namespace doesn't seem to 
work.  dovecot 2.0.8

mail.warning] imap(tom2): Warning: Subscriptions file

from .subscriptions:
~/mail/foo1/folder1
~tom2/mail/foo1/folder1


in 10-mail.conf
namespace {
   type = private
   separator = /
   prefix =
   inbox = yes
}
# for backwards compatibility:
namespace {
   type = private
   separator = /
   prefix = mail/
   hidden = yes
   list = no
}
namespace {
   type = private
   separator = /
   prefix = ~/mail/
   hidden = yes
   list = no
}
namespace {
   type = private
   separator = /
   prefix = ~%u/mail/
   hidden = yes
   list = no
}



What's funny is that it appears to work with a preauthenticated session 
or by using openssl to connect to port 993.

We're seeing this with at least thunderbird and outlook.
