Quote:@dnsbl_score (default: see below)
A list of RBLs to be checked. If you want that a host is not
being evaluated any further if it is listed on several lists or
a very trustworthy list you can control a immediate REJECT with
$MAXDNSBLHITS and/or $MAXDNSBLSCORE. A list of RBLs must be
build as follows:

@dnsbl_score = (
RBLHOST1, HIT SCORE, MISS SCORE, LOG NAME,
RBLHOST2, HIT SCORE, MISS SCORE, LOG NAME,
...
);
The default is:

@dnsbl_score = (
"pbl.spamhaus.org", 3.25, 0, "DYN_PBL_SPAMHAUS",
"dnsbl.njabl.org", 4.25, -1.5, "BL_NJABL",
"bl.spamcop.net", 1.75, -1.5, "SPAMCOP",
"sbl-xbl.spamhaus.org", 4.35, -1.5, "SBL_XBL_SPAMHAUS",
"list.dsbl.org", 4.35, 0, "DSBL_ORG",
"ix.dnsbl.manitu.net", 4.35, 0, "IX_MANITU",
"relays.ordb.org", 3.25, 0, "ORDB_ORG"
);
