1.. _imap-admin-locations-hashing: 2 3Directory Hashing 4================= 5 6Cyrus IMAP uses directory hashing for per-user state information, 7including quotas (with ``quota_db: quotalegacy``), sieve, subscriptions 8and seen information. Sites with lots of users may wish to hash their 9mail spool, too. Cyrus provides mechanisms for this. This pair of 10settings for :cyrusman:`imapd.conf(5)` control hashing behavior: 11 12.. include:: /imap/reference/manpages/configs/imapd.conf.rst 13 :start-after: startblob hashimapspool 14 :end-before: endblob hashimapspool 15 16.. include:: /imap/reference/manpages/configs/imapd.conf.rst 17 :start-after: startblob fulldirhash 18 :end-before: endblob fulldirhash 19 20Regardless of those settings, the per-user state information will 21always be hashed. 22
