<dnsbl name="dnsblname" domain="dns.domain.org" action="KILL" reason="youre banned!" duration="1d" bitmask="5">

Where the attributes are as follows:

• name: A readable name for the blacklist, e.g. Blitzed OPM
• domain: the dns domain the bl uses, e.g. opm.blitzed.org
• action: one out of KILL, ZLINE, KLINE, GLINE (case sensitive!)
• reason: any text you want to use as banreason or tag (%ip% will be replaced by the user's ip)
• duration: how long you want to enforce the ban (takes no effect on KILL)
• bitmask: For bitmask type blacklists, this is an AND mask the result from the rbl is masked again, e.g. if you only want results 1 and 4, enter 5(=1 | 4) here. Must be greater than 0 (use 255 for matching all Class C backlist results)
