3Directory Hashing
4=================

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.
