[Dovecot] utility to update indexes ?
We have both dovecot and a webmail application that are both modifying our users maildirs, so dovecot indexes can be out of sync when the webmail has been messing with the maildirs. We also have a webservice that report how many unread messages a user has in his inbox, which is simply counting files in the maildirs (plus caching the result, and present old values if the directory timestamps hasn´t changed).
I think this checking of unread messages webservice would be much nicer on the filesystem if it instead used the dovecot indexes, so I created a small utility based on utils/idxview.c that do that: http://blag.tanso.net/code/unread.c
But this woun´t work if the maildir has been modified outside of dovecot (i.e. webmail usage). Are there any simple interface I can use in this short snippet for noticing that the index is out of sync, and update it ?

With v2.0 you could use doveadm easily (you can also just use doveadm binary from v2.0 and keep using v1.2 elsewhere):
doveadm mailbox status unseen inbox
If you're actually running v2.0 you can also ask this information via UNIX/TCP socket.

This sounds great, but I'm struggeling to get it working... It complains about:
$ doveadm -v mailbox status -u user@example.com unseen inbox doveadm(user@example.com): Error: userdb lookup: connect(/usr/local/dovecot-2.0.9/var/run/dovecot/auth-userdb) failed: No such file or directory doveadm(user@example.com): Fatal: User lookup failed: Internal error occurred. Refer to server log for more information.
Will I need to have the dovecot-2 daemon running for this to work ?
My config was quickly converted from v1.2 by "dovecot -n > new.conf" and very little modifications..

But get the exact same errors..

This needs to be able to connect to v1.2's auth-master socket. So first problem is to make it look in the correct directory:
base_dir = /var/run/dovecot
(or wherever your v1.2's base_dir is)
Then you'll also need to configure v1.2 to add auth-userdb socket on top of auth-master socket (if you didn't already have it). http://wiki.dovecot.org/LDA describes how to add auth-master socket. Just name it auth-userdb instead of auth-master.

I already had a /var/run/dovecot/auth-master, so I just created a symlink to it from from /usr/local/dovecot-2.0.9/var/run/dovecot/auth-userdb and now doveadm works. Thanks again!

Easiest would be to just use a webmail app that talks IMAP and let it talk directly to dovecot... ?

Yes, we want to implement that as soon as possible. Looking forward to getting everything all maildirs completely managed by dovecot.
