Using hash directories

[Emmanuel Lacour <elacour@easter-eggs.com>]

Hi,


I would like to understand why some softwares such as postfix or squid
uses hash of directories like:

a/a/
b/a/
c/a/
d/a/darmond
e/a/
f/a/


for their spools.

I will set up a server for a lot of mail accounts (~20000) with
postfix+ldap+maildrop+courier-imap, so is it better to put all Maildirs
in /home/vmail/ directly or using hash directories? What are the
benefits?
