Aside from spam it is one of the reasons why I reject all mail to the list
address that does not origin from the listserver. His backscatter can be
rejected by checking the helo: dothangizmo.gk.lan

215 rejects from that address alone (he is also subscribed to the German
opensuse-de list) in about one hour.

I started with a server on a dynamic ip as well. But I hope I wasn't as
trigger-happy as Martin.

I'm using ipcop as firewall. Just searched for the possibility to
blacklist an ip without luck. I guess you can only do that with custom
rules on the command line.

Can you set up rules for outgoing traffic in Shorewall?
