Ok, lets get back on topic: (some cisco config for network operators:)
SORBS is relay testing again (see bounce below). BTW: for those networks
that only feel comfortable blocking illegal activity, this is a violation
of CAN-SPAM, because the message forges email headers, which is banned.
You can access list the scanners by the following:
access-list 104 deny ip 203.15.51.42 0.0.0.31 any
Its more effective to block the DNS servers for the blacklist:
access-list 104 deny ip host 194.109.9.11 any
access-list 104 deny ip host 194.134.35.168 any
access-list 104 deny ip host 194.134.35.204 any
access-list 104 deny ip host 204.152.186.189 any
access-list 104 deny ip host 203.15.51.34 any
access-list 104 deny ip host 209.209.1.20 any
access-list 104 deny ip host 209.142.2.10 any
access-list 104 deny ip host 194.134.64.74 any
access-list 104 deny ip host 128.193.0.30 any
access-list 104 deny ip host 128.193.0.130 any
