There were some problems related to this in dbox, although in your case
it seems to be worse than what it should..

I've anyway done several fixes in v2.1. Can you try if these problems
happen with it too? And in any case cleanup the dbox from the *.broken
files, so that "doveadm force-resync" won't give any errors.
