<DIV><FONT face=Arial size=2>What are the security implications of someone
hacking a DNSBL (Real-time-spam-block-list) and changing the block list to
include (deny email from) some very large portion or all IPv4
space? </FONT></DIV>
<DIV> </DIV>
<DIV>Given that a signifigant number of the spam blocking lists seem to operate
on a shoestring budget in someone's basement, how can we be assured that they
have sufficient resources to secure their systems adequatley, and monitor for
intrusion 24x7?</DIV>
<DIV> </DIV>
<DIV>Unless I am missing something, this would seem to be a real handy and
centralized method for someone to interfere substantially with
the proper operation of a few thousand email servers and hold up global email
traffic for a few hours.</DIV>
