Package: dovecot-imapd
Version: 1:1.0.15-2.2
Severity: normal
Tags: patch fixed-upstream
The current version of dovecot in testing and unstable has a bug that does not
allow storing private \Seen flags for messages in shared, read-only mailboxes,
although the control and index files are specified to lie in the users' private
namespace (and thus are user-writable).
This is a known bug in dovecot [1] and it has been fixed upstream in the 1.1
branch [2]. The patch in [2] is backportable to 1.0.15 and seems to function
well.
Steps to reproduce:
1. Define a read-only shared mailbox as a public namespace:
namespace public {
separator = /
prefix = Public/
location =
maildir:/home/public-mail/Maildir:CONTROL=~/Maildir/control/public:INDEX=~/Maildir/index/public
hidden = no
}
and create some maildirs underneath it.
(The above is documented in Dovecot's Wiki as a recommended procedure[3])
2. Give read-only access on /home/public-mail/Maildir and its subdirectories to
a group specified in mail_access_groups in dovecot.conf.
3. Tag messages in the subfolders of Public as read
4. Change folders: the mail server reports "OK Store ignored with read-only
mailbox" and changes are not preserved upon leaving the folder.
