How is your "mail_location" defined in your configuration? And what is your search term?

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.

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!

John

Those files are most likely leftovers due to failed operations, for reasons like crashes.
