Hi!
That same page i added a zillion times with all kinds of .biz ones, so sure, in those cases it will work. But! Most likely a REGULAR rbl would also block those.
Not really. These are spammers using fresh trojaned home computers and non-blacklisted Chinese/Korean/Brazil/Russian/etc IPs to send their email.
I mean, the IP is listed as spamnest, and even spamcop could list it, as the IP op the spamvertized site.
If you list them there.
Listing almost all of the relays used by spammers is hard. Listing almost all of the domains in URIs used by spammers is less hard. Listing almost all of the NS servers for those domains is even less hard. At least at the moment...
Sure :) Got the point.
Currently i think a mix of the above, and some local rulesets to detect the Vi@gra crap that will make things happen....
Thanks, Raymond.
