Watch out for any
IN_IPv6_RBL scores in your policyd-weight logs.
If you see regular hits, you probably have to either upgrade your policyd-weight or disable rbl.ipv6world.net manually.
Here is a brief howto for Debian-based installations:
- First generate a configuration file, if you are missing one:
policyd-weight defaults > /etc/policyd-weight.conf
- Put a comment before rbl.ipv6world.net:
... ## DNSBL settings @dnsbl_score = ( # HOST, HIT SCORE, MISS SCORE, LOG NAME 'pbl.spamhaus.org', 3.25, 0, 'DYN_PBL_SPAMHAUS', 'sbl-xbl.spamhaus.org', 4.35, -1.5, 'SBL_XBL_SPAMHAUS', 'bl.spamcop.net', 3.75, -1.5, 'SPAMCOP', 'dnsbl.njabl.org', 4.25, -1.5, 'BL_NJABL', 'ix.dnsbl.manitu.net', 4.35, 0, 'IX_MANITU', # 'rbl.ipv6-world.net', 4.25, 0, 'IPv6_RBL' ); ...
- Restart policyd-weight:
