[Dovecot] Shared namespace, separator, username and dots.

[Marcio Merlone]

Hi folks,

I run a legacy mailserver that i had replaced courier-imap for dovecot 
1.2. Everything is fine except for shared namespace. Maildir structure 
has been created using dot '.' as folder separator. It happens that all 
our users are created as name.surname as default. So when I want to 
select a shared folder, MUA end up with the following IMAP command:

select shared.jhon.doe.folder.subfolder

Obviously I took ages to figure why it won't work since it takes 'doe' 
as a folder and not a username part. When sharing a folder from 'sales' 
user, for example, it works fine.  What do you suggest to make shared 
folders work for all without rebuilding hundreds of maildirs to change 
folder separator from '.' to '/'?

Thanks for any hint.
