[imp] Show quota in imp

[Miky]

Dear Horde team,

    Would you tell me how to configure IMP to show quota in login page.

Here are my detail:
    I use sendmail-8.12.5-7 , imap--2001a-15 , horde-2.2 , imp-3.1.
    when I telnet to localhost 143 I get

* OK [CAPABILITY IMAP4REV1 LOGIN-REFERRALS STARTTLS AUTH=3DLOGIN] =
localhost.localdomain IMAP4rev1 2001.315rh=20

    I use Redhat 8.0
    I can use horde and imp properly but just want the quota feature.

Regards,
Miky=20
