[Dovecot] problem with subscriptions file version 1.0.1

[Liz]

I had noticed MAILDIR_FS_SEP, but it did not seem (perhaps I am 
mistaken?) as though any of the places it occurred were adding dots to 
the beginnings of directories. When I pulled up the list of possible 
folders to subscribe to in Thunderbird, the new folders were there and 
they were checked, presumably indicating they were subscribed to 
already. So I unchecked them and rechecked them again and then they were 
visible.

I used wireshark to see what dovecot and Thunderbird might be saying to 
each other and nothing appeared broken there. The responses to the list, 
subscribe, lsub and create requests were all "OK", in any case. Deleting 
folders works fine as well.

The suggestion of adding dots to the beginning of the internal files was 
also a good one.

Thanks for your reply,
Elizabeth Bermel
