I'm with Luca.
in general blacklisting is an unprofessional, trivial security concept and completely sucks,
Netblock: 18.104.22.168/24 (22.214.171.124-126.96.36.199)

they still block my mail server on .246 cause some spamfucks were once in my assigned netblock??? great.
and blocking Luca against their own(!) whitelist policy is really scandalous.
I and many people can't simply afford the horrific costs of static and NIC registered IPs.
this is social discrimination of internet users and glorifying the few big mailprovider's monopoly
all in the name of a "protection system" that has been long proven of complete failure by spamgangs.
Jim, so how to prove ownership of a IP? thats actually a crap requirement, cause only the ISP
can certify. NIC registry can't, too. I can register every fake data in there. spamgangs do so.
CA signed server certificates can't prove ownership of an IP, too, cause I could use any proxy
and fake certify ownership of its IP that way. so practically you never get delisted from sorbs,
once listed. they don't do blacklisting, actually they do whitelisting in their big sponsors preferences(?) in fact.
besides this is a violation of accepted civilized international law principles. pre-convicted for having done
nothing. BTW law: in most countries courts take denied mails *as delivered*(!) to evidence whatever the reason for denial!
so companies be very careful using blocklists...
sorbs: "Fighting spam by finding and listing Exploitable Servers.". real great policy. Which administrator
can assure that his systems are 100% unexploitable all the time? this is pure SCI-FI and not a
accepted all day practioneer's requirement.
as Luca said, spam-gangs avoid it easily. Johannes, PLS use a bayesian filter / greylisting combination.
or use spamhaus at least. they have a much kinder not "ordinary dynamic IP internet
mail user discriminating" delisting policy :)
with private house community wlan-routers, wifi-hotspots, inetcafes, anonymizers further upcoming,
blacklisting has become complete idiocracy. sorbs go on, blacklist them all!
spamgangs laugh at You.
