Nepenthes configuration

I am currently running nepenthes in order to collect the various malware that scan my IP address everyday. I have succesfully installed it and changed the submit-norman.conf file to include my email address. However, when I check the logs there is nothing in the logged_submissions, and just one entry in the logged_downloads. However, when I check the hex dumps there are quite a few entries there in bin format but nothing in the binaries folder. Any ideas what is going on?
