Hi Sascha

It might be always a problem in shared namespace
( i think depended to maildir spezifications )
to share all thinkable usernames
i.e ich have maildirs from users like user.name at domain.org
seperator switch changing does not help for all cases
i may be wrong here, but i think cyrus fixes this by mapping
problem chars in mailbox names on the fly with , i also remember
a dovecot patch in the download area for fixing like this problems

i tried to use dbox format for get out of this Problems but i cant get
dbox to work for real use in all possible cases of my full virtual
domain setup, but i think it might be the best solution using dbox
getting out of char problems with shared public user mailbox names
as a dir full virtual mail domain struktur should look like this
( comming from postfixadmin ) ie. in file system
/usr/local/virtual/domain.de/user at domain.de
this should make it possible not just share between users
of the same domain, but creating shares cross all hosted domains/users

all belong to virt user vmail:vmail and managed over mysql ( perhaps ldap )
