I honestly haven't a clue... I don't have these on my server at all.

I would probably just nuke these files, but maybe after confirming
what their contents really is.  

Gionatan> An example of a folder with 6 .temp files:

I really don't know, sorry!  I'd have to got poke at the source to see
how they're created and where. I don't use dbox, I use Maildir for my
setup.

So I suspect (but I'm not sure!) that these are just leftovers from
mailbox accesses which got left behind.  Try googling for 'dovecot
dbox temp files' and maybe that will help.  Sorry!
