dovecot - Jan 2006 - beta1: how to use quota plugin???

Hi,
    After searching gmane.mail.imap.dovecot on the topic, and 
wiki.dovecot.org, I'm still clueless on how to use RFC 2087
quotas in dovecot with the quota plugin.  How come no wiki
doc?

My setup: Solaris 9, mbox format.  Both the filesystem for
INBOXes (/var/mail) and the user's home directories have 
filesystem-based quotas imposed.  For example:

% quota -v joeblow
Disk quotas for joeblow (uid 20737):
Filesystem     usage  quota  limit
/export/home     955 298000 302400  (where indices and mail folders go)
/var/mail        530 151200 204800  (where joeblow's INBOX lives)

If joeblow connects via dovecot IMAP, I want our webmail code
(horde/imp) to tell him his disk quotas to keep him out of
trouble.  Horde/Imp (2.2.5) has quota code that says it works with
Courier imap.  Dovecot is supposed to be Courier compatible.
How do I get the quota info out of Dovecot and down to Horde/IMP?

I haven't yet managed to make it work myself either. Although I got as far
as my system telling me that it doesn't support quotactl() syscall.

The point is anyway that userdb should be providing a "quota" named
variable
to Dovecot. So it doesn't even work with all userdbs yet. I'll probably
have
to add some other place to set it up also (similar to default_mail_env).
Anyway, its format should be:

quota=fs:/home/user/mail

Or if all of the users are in same quota root, I suppose fs:/home works just
as well.

Well, Dovecot is mostly Courier compatible in its Maildir handling. I'd
think the quota plugin is RFC2087 compatible and having nothing
Courier-specific.
