What works for me is to create a header with the default and then to
create a data file. Here's an (inelegant) example:

        rbl="/var/lib/rbldns/dsbl"
        grep "Recipient address rejected" /var/log/maillog.1 >$rbl/temp
        grep -e "helo=<.*tqmcube\.com>" /var/log/maillog.1 >>$rbl/temp
        grep -oE "[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}"
        $rbl/temp >$rbl/temp2
        sort $rbl/temp2 >$rbl/temp3
        uniq $rbl/temp3 $rbl/temp
        cat $rbl/temp |mail -s "Updated RBL Clients" root
        grep -oE "^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}.*"
        $rbl/rblclients >$rbl/data
        cat $rbl/temp >>$rbl/data
        sort $rbl/data >$rbl/temp
        uniq $rbl/temp $rbl/data
        cat $rbl/header >$rbl/rblclientstemp
        cat $rbl/data >>$rbl/rblclientstemp
        mv -f $rbl/rblclientstemp $rbl/rblclients
        chown rbldns:rbldns $rbl/rblclients
