Onderwerp: spamblocker turns into mail denial of service

At some point in the last 24 hours the dns-based blackhole list
proxies.relays.monkies.com turned into a deny-all-mail: the A record
for the blackhole list is now 127.0.0.2 which means all mail is rejected.
Anyone who knows anyone who was using this should immediately remove
it. I do not know why the folks at infinite monkeys would do this nasty
thing, perhaps it was done by a spammer hacking in.

Certainly it points out that all such services should be using DNSSEC
and that perhaps that's not enough if the name server is hacked.

Howdy,

The Monkeys.com blacklist was officially retired 9/22 due to repeated
DDoS attacks on it's main servers.

Please see http://www.dnsbl.info/forums/topic.asp?TOPIC_ID=3D12 for the
official closing announcement from Ron Guilmette.

Cheers!

Glad I'm not the only IT guy on the planet who noticed this.
The first message I rx'd that was tagged as on the infinite monkey
dnsbl was at 03:00 EST (GMT-5) today, since then all incoming email
has been tagged as spam.

I removed the infinite monkeys DNSBL from my config and we are back to
normal.

I should have done this back in Sept last year.

Thanks for confirming my suspicions
