dovecot - May 2010 - question about rpc quota reporting 1.2.11

Timo, thank you for the reply to my question about shared folders yesterday.

I'm now trying to get quota reporting working consistently.  This is 
with dovecot 1.2.11 in solaris 10 sparc.  We have local quotas for the 
mail spool (/a1) and quotas for home directories.  All are UFS and have 
rpc (rquota) working fine.

With just this:

protocol imap {
   mail_plugins = quota imap_quota
}

My mail client (thunderbird 3.0.4) reported the home directory quota.

So then I added this:

plugin {
   quota = fs:INBOX:mount=/a1
   quota2 = fs:Home:mount=%h
}

First, I had to make /a1/quotas world readable, otherwise I'd get this 
error:

   open(/a1/quotas) failed: Permission denied

I'm getting the same type of error with the quota2 line now:
   open(/nfs/rack/u4/quotas) failed: Permission denied

Since the home directory quota worked without the plugin configuration, 
my guess is that the plugin config is not using rpc.  I can't find any 
way to force it to use rpc.  Again, if I make that 'quotas' file world 
readable (which I believe isn't good practice), dovecot stops complaining.

Also, what should I expect to see on the client?  Will dovecot report 
only one quota (the one that's closer to the limit), or will it report 
both?  I've only seen the first quota in thunderbird, but that could 
easily be a client issue.

thank you

Dovecot first finds the mountpoint and then gets its filesystem. If it's
nfs, it uses rquota, otherwise local quota. You could enable
mail_debug=yes and see what mountpoints Dovecot finds and then see if
their type is nfs or something else. Also this would make checking the
type (correctly) even easier: 
http://hg.dovecot.org/dovecot-1.2/rev/eaba4cfeaa44

yes, that seems to have done the trick.

thank you
