Strange that no-one had complained about this before. The problem is
that your kernel is caching writes and it doesn't know the user is over
quota. So then when fsync() finally gets called the kernel writes the
data to NFS server, which replies that quota exceeded.

This fixes it: http://hg.dovecot.org/dovecot-1.0/rev/9879434a6339
