I tried this setup:

namespace {
   type = private
   separator = .
   prefix = Archive.
   location = mdbox:/home/%u/archive
   #subscriptions = no
   #list = children
}

plugin {
   quota = dict:User quota::proxy::quota
   quota2 = dict:Archive quota:ns=Archive.:proxy::quota
   quota2_rule = *:storage=1048576
}

telnet localhost 143
1 login .. ..
2 list "" *
* LIST (\HasNoChildren \Sent) "." "Sent"
* LIST (\HasNoChildren \Trash) "." "Trash"
* LIST (\HasNoChildren \Junk) "." "Junk"
* LIST (\HasNoChildren \Drafts) "." "Drafts"
* LIST (\HasNoChildren) "." "INBOX"
* LIST (\Noselect \HasChildren) "." "Archive"
* LIST (\HasNoChildren) "." "Archive.Test"
2 OK List completed.
2 getquotaroot ""
* QUOTAROOT "" "User quota" "Archive quota"
* QUOTA "User quota" (STORAGE 259 7540259)
* QUOTA "Archive quota" (STORAGE 2109 1048576)
2 OK Getquotaroot completed.

So the configuration is running in Dovecot v2.1.13. The value of "User 
quota" comes from LDAP. What I did not tested was, if the quota is 
actually calculated and tracked in the database.

Kind regards,
