dovecot - Oct 2010 - help with expire plugin

Dear All,
              I am using version 2.0 and willing to use expire plugin
in my setup but unable to set it up correctly. Here is the relevant
part from output of doveconf -n

# 2.0.0: /usr/local/dovecot/etc/dovecot/dovecot.conf
# OS: Linux 2.6.26-2-686 i686 Debian 5.0.6
base_dir = /usr/local/dovecot/var/run/dovecot/
dict {
  expire = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext
}
mail_plugins = quota acl expire virtual

namespace {
  inbox = yes
  location   prefix   separator = .
  type = private
}

plugin {
  expire = Trash 7 Spam 30
  expire_dict = proxy::expire
}

}

protocol imap {
  mail_plugins = $mail_plugins imap_acl autocreate imap_quota
}


I have also created the database and tables for mysql and made the
following change in dovecot-dict-sql.conf.ext file

connect = host=localhost dbname=mails user=root password=xxxxxx

map {
  pattern = shared/expire/$user/$mailbox
  table = expires
  value_field = expire_stamp

  fields {
    username = $user
    mailbox = $mailbox
  }
}


I am not getting any error in log file and expire is not working too
please let me know the issue ...

Thanks

Lots of fixes since 2.0 was released... please update first, then try
again...

This is not v2.0-compatible configuration. Read the wiki page.

Also note: "Unless you have thousands of users, you probably shouldn't
bother with this plugin."
