Automated RBL Check

Ok, I wrote a powershell script that will check a list of IPs against rbl-check.org and return any RBLs that have the given IP listed. 

$IPList = "x.x.x.x","y.y.y.y"  # The list will need to be supplied by Lomo. 
foreach($IP in $IPList){
    $result = Invoke-WebRequest http://rbl-check.org/rbl_api.php?ipaddress=$ip -UseBasicParsing
    $rbl = $result.content.split("`r`n") | Select-String -Pattern '\;listed'
    if($rbl){$output = $rbl}
}
if($output){return $output}else{return 0}
 
Now I have to go re-learn how to write custom datasources and covert the above to work with Lomo. Then I think I have what I waned. Automated alerts if a supplied IP is included on any RBL list. (At least any RBL list that rbl-check.org  searches.)
