[c-nsp] SMTP

[Drew Weaver]

What is stopping service providers having a bunch of perl scripts that 
daily check when IP's they are responsible for get listed?  It should be 
simply an extension of their NMS platform.  Once you have detailed 
WHOIS/PTR records you at least have something to point out to the 
postmasters, and the blacklist maintainers, to say "hey next time do 
*your* jobs properly". :)

Er, are you serious? 

Sending 90,000 DNS queries to all the different RBLs on a daily basis is an easy way to get banned your network banned.
