It works with the following settings.

mail_location = maildir:/usr/local/virtual/%d/%n/

namespace {
  hidden = no
  inbox = yes
  list = yes
  location =
  prefix =
  separator = /
  subscriptions = yes
  type = private
}

namespace {
  inbox = no
  list = children
  location = maildir:/usr/local/virtual/%%d/%%n:INDEX=/usr/local/virtual/%d/%n/shared/%%u
  prefix = shared/%%d/%%n/
  separator = /
  subscriptions = no
  type = shared
}


I have read the the wiki and tried to use the home folder.
I created a dir /usr/home/virtual/ gave it the right permissions.

But the wiki is not very clear (for me ) where i must alter my config
to use the home dir.
In my understanding , i must set the home dir by doing the following.
mail_location = maildir: home=/usr/home/virtual/%d/%n/
mail=/usr/local/virtual/%d/%n

But the i get a few errors

also when sending mail, i get the following error
