I'm certain Dovecot didn't create this file at least directly.

This is a dotlock and it can be created by Dovecot. You could also  
probably disable it. http://wiki.dovecot.org/MboxLocking http://wiki.dovecot.org/MailboxFormat/mbox

Hmm. NFS is a pretty good suspect here. I know that in some situations  
it creates such temp files, although they're usually  
named .nfs.something. Are those files deleted or are they just lying  
around? What size do they have?
