New IP4R lists available for use

[Bill Landry <bi...@pointshare.com>]

Folks, I would like to announce the availability of a new IP4R database that
includes a blacklist, whitelist, suspicious list, and a neutral list (IP
address that have not been classified).  Here is the breakdown on the list
usage:

Service hostname: pub.senderdb.net

127.0.0.2   Black List
127.0.0.3   White List
127.0.0.4   Suspicious List
127.0.0.5   Neutral List

They will be updating their web site today with some documentation and
contact info, but you can access it now at www.senderdb.com.

A little history about the company providing these new list:

The parent company is Solid Oak Software, the developers of the popular
Cybersitter parent filtering software.  About a year ago they came out with
a new spam-filtering gateway product call Alligate (www.alligate.com) that
was largely developed around their Cybersitter technology.

Throughout that year they realized that with over 500,000 mailboxes being
filter by Alligate gateways, they had a very large pool of data to work with
in putting together some large and very accurate IP4R databases, which
spanned the database lists above.

So, in an effort to give something back to the spam-fighting community, they
decided to make these lists freely available.  I personally have no
affiliation with the company, other than I have worked with then to test
several of their products over the past two years.  I have been using their
new IP4R lists for about two weeks now, and have found them to be very good
(high hit counts) and extremely accurate.

And in case you're wondering, yes, I did ask if I could announce the
availability of these new databases on these various lists and was given
approval, so have at it...

I did a quick mass-check run over a spam corpus of mails I received
during the last three days. Unfortunately I don't have enough ham here
to check that, too.

RCVD_IN_SENDERDB_BL 267/456 spams (59 %)
RCVD_IN_SENDERDB_WL 44/456 spams (10 %)
RCVD_IN_SENDERDB_SL nothing

The whitelist seems to be quite inaccurate... 10% of spam hit by a
whitelist is a lot.

Over the same period of time, the SpamCop BL hit 380/466 spams (82 %).
Just for comparison.

I'm adding RCVD_IN_SENDERDB_BL to our local rulesets for the next few
days to see how it does.
