Our blackhole lists are defunct. We announced their closure over 2 years ago and it was
widely covered by the press at the time. We are still recording several hundred lookups
per minute so Friday December 9th 2005 we started answering positive to all requests. If your
mail is being blocked simply contact any isp blocking you using these lists and let them
know they need to remove them ASAP! If they have questions they can contact me directly.
My email is firstname.lastname@example.org
To identify whom to contact please reference the error message you receive.
Look for something similar to:
I announced this upcoming change to both the SPAM-L mailing list and the
"Over 2 years ago I shutdown blackhole.compu.net, pacbelldsl.compu.net, and pm0-no-more.compu.net
then announced the shutdown on the news.admin.net-abuse.email and several other mail and abuse
related lists. As of today I am still logging several hundred requests per minute to it two
years later. In one week I am going to start answering positive on every lookup to those domains.
I don't want to do this however I am not going to continue to bear the load for something that
ceased to exist over two years ago. So basically check your mail servers and if you are using
the blackhole.compu.net, pacbelldsl.compu.net or pm0-no-more.compu.net dnsbls remove it asap!
----- Transcript of session follows -----
... while talking to mail.somedomain.com.:
>>> MAIL From:<email@example.com>
<<< 518 Your SMTP server is listed at something.compu.net
554 5.0.0 Service unavailable
In this case you would contact somedomain.com you would tell them that the
whatever.compu.net dnsbl is defunct and is now answering postiive on all
lookups. As such they should remove it and any other compu.net dnsbl ASAP to
prevent legitimate emails from being blocked.
If they need verification send them to this web site.
