We just setup a new mailserver using Bill's Toaster and are now seeing these strange files in the /home/vpopmail/etc directory:

-rw-r--r--    1 root     root            0 Apr 20 00:01 open-smtp.tmp.738
-rw-r--r--    1 root     root            0 Apr 16 01:38 open-smtp.tmp.739

They have zero size and do not seem to be expiring. We are using vpopmail with roaming user support and courier-imap. We're not sure what's creating these files. They don't exist on non-courier-imap mailservers.

Any ideas on where they are coming from or what we did wrong? We can write a cronjob to delete them but I thought I would ask in case we messed something up.
