Thank you for letting us know!

It seems that 255.254 and 255.255 codes are indeed in the configuration
whilst 255.252 code is missing:

returncodes {
        SPAMHAUS_SBL = "127.0.0.2";
        SPAMHAUS_CSS = "127.0.0.3";
        SPAMHAUS_XBL = ["127.0.0.4", "127.0.0.5",
            "127.0.0.6", "127.0.0.7"];
        SPAMHAUS_PBL = ["127.0.0.10", "127.0.0.11"];
        SPAMHAUS_DROP = "127.0.0.9";
        SPAMHAUS_BLOCKED_OPENRESOLVER = "127.255.255.254";
        SPAMHAUS_BLOCKED= "127.255.255.255";
}

Is there anything that could cause "Typing error in DNSBL Name" that
could be not a general configuration fault?
