[Dovecot] Quota

[nuno marques]

hi,
 I'm having some difficulty understanding the connection between postfix, dovecot and quota.
 What is the best way to set up quotas? through the file system quota and maildir? Need the dovecot lda working? The postfix needs a patch?

 I was thinking about setting quotas on file system, then configure Postfix to connect to dovecot-lda. Any suggestion?

 The system as a whole is composed of:dovecot-2.0-0.10.beta6.20100630.el6.x86_64 -> 2.0.beta6 (3156315704ef)openldap-servers-2.4.19-15.el6_0.2.x86_64postfix-2.6.6-2.1.el6_0.x86_64mailscanner-4.84.3-1.noarchspamassassin-3.3.1-2.el6.x86_64centos 6 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 x86_64 x86_64 x86_64 GNU/Linux
