News and changes at Project UCEPROTECT-Network12.12.2011
We introduced the pillory at our website so that anyone can see all of those black hat providers that managed to be currently listed in UCEPROTECT-Level 3.
We recommend to
Policies for Levels 2 and 3 were adjusted to be more effective against well known long time spammers.
Since UCEPROTECT-Network started to publish it's downloadable blocklists in RBLDNSD format (03.07.2007) almost all of our users which are using downloadable formats have switched to download RBLDNSD via RSYNC.
Also UCEPROTECT-Mailserver Software is using the RBLDNSD format since V4.0
Therefore the other formats (Postfix / Sendmail access, Qmail, UCEPROTECT-Software Version 3.5 and older) and also the HTTP download option via WGET became obsolete and will no longer be offered after 01.01.2010
If you are still using these formats or if you download via WGET, we strongly recommend that you switch to using us either via DNS or to download our blocklists via RSYNC in RBLDNSD format only.
Details how to use RSYNC and RBLDNSD can be found here.
UCEPROTECT-Network now maintains a HIGH-TRUST whitelist too.
For details see:
We have installed a feedback-loop for interested companies or providers.

Project UCEPROTECT-Network has chosen to mirror it's own zones (UCEPROTECT Level 1, 2, 3) and BACKSCATTERER.ORG zones only.
Other lists form external vendors formerly mirrored by us were dropped
Project UCEPROTECT-Network now offers all zones available also for download with RSYNC in RBLDNSD format.
Details how to use RSYNC can be found here.
UCEPROTECT-Level 1 was cleaned up, and is now one of the most accurate and reliable blacklists again.
UCEPROTECT Level 1 does no longer list backscatterer and sender callout abusers. A new list was established for that reason:

Project Management was changed for quality reasons.
