again, my quota config is this:

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

When I modified the quota-fs.c file, recompiled, and ran in mail_debug 
mode, I get messages like this:

That is the correct quota for my home dir, so it did query via rquota 
eventually.  There just seems to be something happening at login (at 
least) where it is trying via the file system first, even though it 
shouldn't.

thank you
