RBL.CLUECENTRAL.NET is back
Since I stopped maintaining the RBL in november 2005, many, many people
have urged me to restart it. Apparently the RBL is a useful tool used
by postmasters and system administrators to block or whitelist countries
and/or netblocks based on origin AS number.
I am not going to give up and will retaliate spammers with every possible
measure I can take. Reopening this RBL is one of them.
The current version is completely based on the data provided by:
All IP-to-ASN information is extracted from a full BGP-view.
The RBL has 2 ways of listing: one by AS, one by country. Examples:
66.0.136.213.NL.rbl.cluecentral.net
66.0.136.213.AS12859.rbl.cluecentral.net
You can configure your mailserver to use (by example):
kr.rbl.cluecentral.net (blocks mail originating from Korea);
AS31064.rbl.cluecentral.net (blocks mail originating from AS31064;
You can use as many lists as you want.
Announced IP-space which did not match an AS number listed in one of the
RIR's statistics-file are listed as country UN. All other countries are
listed by their official CC-code.
All matches return 127.0.0.1 without TXT record. I choose not to add a
TXT record since that will leave me with lots of "unsubscribe"-requests,
which are naturally not possible.
