If enabled, uses an improved directory hashing scheme which hashes on the
entire username instead of using just the first letter as the hash.  This
changes hash algorithm used for quota and user directories and if
*hashimapspool* is enabled, the entire mail spool.

Note that this option CANNOT be changed on a live system.  The server must
be quiesced and then the directories moved with the **rehash** utility.
