I have a dovecot IMAP server (version 2.1.7) with Maildirs and a virtual user setup (e.g. all accounts are mapped to the same system user). I’d like to create a public namespace shared between users A
and B
, but not any other user.
I tried to set up the namespace as follows:
namespace {
type = public
separator = .
prefix = INBOX.XFeeds.
location = maildir:/var/vhosts/feeds:INDEX=~/Maildir/feeds/
subscriptions = no
}
together with a acl-file:
/var/vhosts/feeds $ cat dovecot-acl
user=A lrwstipekxa
user=B lrwipk
Now user C
cannot access the contents of the XFeeds mailbox, but it still hows up in its IMAP client. How can I make sure that other users cannot observe that this namespace exists?
