    Just use commas
    For example:
    zen.spamhaus.org,bl.spamcop.net,psbl.surriel.com,spamrbl.imp.ch,noptr.spamrats.com,escalations.dnsbl.sorbs.net,bl.score.senderscore.com,bl.spameatingmonkey.net,rbl.realtimeblacklist.com,dnsbl.dronebl.org

    Free rbl providers have connections quota in place.
    By using local caching dns resolver you will typically cache most of the dns response and thus limit connections to rbl servers
