[Dovecot] For Configuration Help: per-user quota for virtual users.

[sales at 100n.org]

Dear dovecot list:

Could any experts help me on the configuration of per-user for dovecot on
FreeBSD 7.x with postfix-2.5.4,1.

I followed the howto of http://workaround.org/articles/ispmail-etch/, it
is an excellent file, my mailserver worked very well.

When I configured per-user quota plug-in, quota_rule with 20MB limits can
not be overrided by the Mysql query statement, Although I followed the
document at :  http://wiki.dovecot.org/Quota.

Below is the output of dovecot --version, dovecot -n and dovecot-sql.conf.
 Could any experts help me?

Thanks in advance !

Best Regards,
Forrest
