I'm running Dovecot 1.2.17 for serving mail via IMAP as well as for
providing access to a mailing list archive. The archive is implemented
as a public read-only mailbox with per-user index files (i.e. the \Seen
flags are per-user).
i guess better upgrade to 2.1.x
first
Given that Dovecot 1.2.17 works fine for me, I actually didn't see the
need to upgrade yet.
I recently enbled the Squat plugin to accelerate searches in the message
bodies and noticed that every user (I'm using a virtual user setup) gets
his own dovecot.index.search and dovecot.index.search.uids copies.
Is it possible to share those files among all users of the system? The
squat plugin appears to store the search indices among the other index
files (as explained on http://wiki.dovecot.org/Plugins/FTS/Squat) no
matter what; I considered storing a central copy of the index files
somewhere and then creating symlinks for all users. It should be ok as
far as file-permissions go since all mail is owned by a single vmail
system user, but I wonder whether the indices are really the same (I
noticed their md5 checksums differ) and whether there may be file
locking issues in case two users search message bodies simultaneously.
Can anybody shed some light?
after upgrade
http://wiki2.dovecot.org/Plugins/FTS/Lucene
may be better choice
Why?
this info might help

Index files
Index files are by default stored under the same directory as mails.
With maildir they are stored in the actual maildirs, with mbox they are
stored under .imap/ directory. You may want to change the index file
location if you're using NFS or if you're setting up shared mailboxes.
You can change the index file location by adding :INDEX=<path> to
mail_location. For example:
mail_location = maildir:~/Maildir:INDEX=/var/indexes/%u
--snip
I already use this; as I mentioned, the index files of the public
readonly mailbox is stored per-user so that each user has his own set of
\Seen flags. Here's my public namespace:
namespace public {
separator = /
prefix = Lists/
location =
maildir:/home/vmail/lists/Maildir:CONTROL=~/Maildir/lists:INDEX=~/Maildir/lists
subscriptions = no
}
Alas, this means that *all* index files (including the Squat index) is
stored per-user whereas I'd just to have just *some* of them per-user. :-)
after upgrade come back, ask again, or meanwhile Timo gives better advice
Does this imply that questions regarding Dovecot 1.2.17 are considered
offtopic on this list? If so, I apologize - I'll look for another forum
then.
