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
http://wiki2.dovecot.org/MailLocation
---snip 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.
