After all the filters that I use were applied - 682 unique IP addresses, with no rDNS sent at least 6124 legitimate (assumed legitimate as not caught by my filters) emails in the period from Feb 2 to Feb 10. This box hosts mail for two large linux lists. And hosts my email, and email for my parents and a few friends.
