1. I stopped "dovecot". 2. I did a ZFS snapshot (play safe!), and disabled incoming messages. 3. I deleted ALL "dovecot.index.cache" (one per mailbox, I have about 500 mailboxes) without any apparent effect. 4. I started dovecot. 5. I moved around with apparently no side-effects. Cache are recreated, small size, growing as you download messages. I still would love an authoritative answer. -- Jesús Cea Avión _/_/ _/_/_/ _/_/_/ j...@jcea.es - http://www.jcea.es/ _/_/ _/_/ _/_/ _/_/ _/_/ Twitter: @jcea _/_/ _/_/ _/_/_/_/_/ jabber / xmpp:j...@jabber.org _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz
