OK understand

seeing prefix always is ok for me

jep i use a full scheme,
/usr/local/virtual/domain/user at domain
which is possible from postfix admin ( which i like to use to admin
mailboxes )
it seems to me as the most logical variant, and it works nice without
using shared namespace yet, but it would be also possible
to use /usr/local/virtual/domain/user
or /usr/local/virtual/user at domain
from postfixadmin i think

but i think it would be more nice to use a full name schema
to make things more clear if i like to use cross domain shared mailboxes
thats why i also wanted to use %d expansion for that, whatever
domain name is a must have cause username may be equal in cross domain
sharing like

/usr/local/virtual/domainA/user wants to share with
/usr/local/virtual/domainB/user
where user is equal so a domainname should be able to be seen
in the client to difference users by equal name in different domains
so if %d expansion dont work in shared
perhaps /usr/local/virtual/user at domain schema
whould be better with shared mailboxes?

also later on i wanted to have a public namespace which should
be later under /usr/local/virtual/domain in the filesystem
but for now that not the point and it wouldnt  be
a problem to have it elsewher like
/usr/local/virtual/public-namespace/domain


set this now

namespace shared {
separator = /
prefix = "shared/%%u/"
location = maildir:/usr/local/virtual/%d/%%u/:INDEX=~/shared/%%u/
subscriptions = no
list = yes
}

but the error seems to stay
is it possible that an @ in the user leads to it ?
( shouldnt be cause %u has no problem with )

but for the first look it doesnt change anything

i will do more tests tommorow
and see if i get more debug
no hurry timo , its alpha phase, but a short
doku should be available when 1.2 going beta
