Hi list,

My IP Address have been listed in the RBL's too many times, I
installed into my linux box MailScanner + Spamassassin + Clamavmodule
+ FProt, I set up the iptables rules allowing only smtp, pop and ssh
traffic, but when I see the traffic with tcpdump I see this strange
behavior:

                [SNIP]

What can I do to stop and block this worm???


Wipe out the OS on 192.168.0.92, reinstall from scratch and apply all patches and updates prior to exposing to the internet. that should clear up the sapm worm.

Thanks,


Ron DuFresne
