warn    message       = X-spam-header: $sender_host_address is in a black list at $dnslist_domain
        log_message   = found in $dnslist_domain
        dnslists      = bl.spamcop.net

If you've got embedded perl, you could try something like:

${perl {check_rbls} {$sender_host_address}}

with

--------8<--------
my @blacklists=qw(
    bl.spamcop.net
    relays.osirusoft.com
);

sub check_rbls {
    my $ip_addr = shift;

    $ip_addr=reverse split /\./ , $ip_addr;

    for my $bl (@blacklists) {
        if( defined ( gethostbyname ($ip_addr . "." . $bl) ) ) {
            return "yes";
        }
    }
    return "no";
}
-------->8--------

Otherwise I can't think of a useful way of doing it.

Sorry
