I'm not sure why you think I am not using skiplist. This file seems to say I am. ella:~# cat /usr/lib/cyrus/cyrus-db-types.active ANNOTATION skiplist DBENGINE BerkeleyDB4.2 DUPLICATE skiplist MBOX skiplist PTS berkeley QUOTA quotalegacy SEEN skiplist SUBS flat TLS berkeley-nosync Also, the directions for upgrading a database, found here: http://www.cyrusimap.org/docs/cyrus-imapd/2.2.13p1/install-upgrade.php under: Upgrading from 2.1.x or earlier General information (ALL SITES) give instructions for using the cvt_cyrusdb program to convert the databases to skiplist: /usr/cyrus/bin/cvt_cyrusdb /var/imap/mailboxes.db berkeley /var/imap/mailboxes.db.new skiplist mv /var/imap/mailboxes.db.new /var/imap/mailboxes.db and the files appear to look exactly the same when you are done as when you start. From the instructions on that page, it looks like I am suppose to use the command on everything with a db at the end, and then on the seen state database. I'm just not sure about the other stuff like __db.001 or the sub files in the same directory as the seen file. Furthermore, these instructions are for an earlier cyrus version then I have (2.1.x vs. 2.2.13), so I'm not even sure this is what I am suppose to be doing. thanks, maria ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
