dovecot - Oct 2008 - Reporting NFS quotas via IMAP

I'm confident that the question has been asked before, but I can't  
remember the answer.

I have
-- dovecot 1.1.2
-- Mail storage (maildir format) on NFS
-- Quotas on that file system
-- A working rquotad
-- mail_plugins = quota imap_quota in the protocol imap section
-- quota=fs in the plugin section

I get (using Apple Mail as a client)
-- Notification that the account supports quotas
-- No information about the size of the quota nor the usage

I probably do something stupidly wrong. The WIKI tells me that fs  
quota support RPC (i.e., rquotad), so I'd expect my client to report  
the quota to me.
Using quota(1) on the mail server works as expected.

Try with manual IMAP commands instead:

telnet localhost 143
a login user pass
b getquotaroot inbox

Does it return correct output? IIRC some clients (maybe Apple Mail?) had
problems listing quota if quota root was empty. If that's the case,
change it (quota = maildir:userquota).

If the getquotaroot doesn't return quota correctly (or at all), set
mail_debug=yes and see what it logs.

Yes, sorry, I should have checked that before.

Yes.

Hmpf. So I was just using a defective client to test my presumably  
defective confuration.

fs:user did the trick. Thanks.

Would this catch be worth being documented in the WIKI?
