[Dovecot] public namespace

Hello,

dovecot -n

# 2.0.18: /etc/dovecot/dovecot.conf

# OS: Linux 3.2.0-2-amd64 x86_64 Debian wheezy/sid

mail_gid = 5000

mail_location = maildir:~:INDEX=/var/mail/indexes/%d/%n

mail_privileged_group = vmail

mail_uid = 5000

namespace {

hidden = no

inbox = yes

list = yes

location =

prefix =

separator = /

subscriptions = yes

type = private

}

namespace {

list = children

location = maildir:/var/mail/vhosts/%d/public:INDEX=/var/mail/indexes/%d/%n/public

prefix = Public/

separator = /

subscriptions = no

type = public

}

i´m a little bit confused but I hope I find help here.

The user mailboxes work perfectly… just the public mailbox is a little bit tricky… I expect that all public maildirs be placed under /var/mail/vhosts/%d/public.

“They are created by defining a public namespace, under which all the shared mailboxes are”.

For those special users, I have set the maillocation via passwd file to /%d/public/%n, all other users have …/%d/%n.

So we have following folder structure

…\public

…\public\.info

…\public\.lager

…\public\.buchhaltung

And so on… That’s works fine, but with subfolder start the problems. When the info-“user” loggs on and creates a subfolder under his INBOX(called hust2) then no other people can see this. Otherside, if a “normal” user creates a folder in public folder info(called hust), the info “user” can´ t see this one.

If I look to filesystem, the reason is clear:

%d/public/.info# ls -la

drwx--S---+ 7 vmail vmail 4096 Jun 21 09:50 .info

drwx--S---+ 5 vmail vmail 78 Jun 21 09:51 .info.hust

A look to the info mailbox makes it clear:

info@BLABLA

            \INBOX

                            \hust2

create by info user in his mailbox

            \Trash

            \Public

                           \info

his own public share

                                           \hust

create by other user in public folder

What I need is:

%d/public/lager/cur

%d/public/lager/new

%d/public/lager/tmp

%d/public/lager/.foo

%d/public/lager/.foo.bar

%d/public/ info /cur

%d/public/ info /new

%d/public/ info /tmp

%d/public/info/.hust

%d/public/info/.hust.deeperhust

%d/public/info/.hust2

All public maildirs under …/%d/public/%n

Must I create a namespace for all public maildirs?:

namespace {

location = maildir:/var/mail/vhosts/%d/public/info

}

namespace {

location = maildir:/var/mail/vhosts/%d/public/lager

}

I can´ t figure out on my own, please give me an explanation.

Thanks for soon comment.
