I searched, but could not find the relevant infomation regarding the mboxkey_db database in 2.3.7 My current 2.2.3 install simply has mboxlist_db as skiplist and this database is /var/lib/imap/mailboxes.db The new 2.3.7 distribution has mboxlist_db as well as mboxkey_db. What is mboxkey_db - is this new and for what is it used? Did this exist in 2.2.3 in some directory which I need to migrate to 2.3.7? thanks S ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
