DNSBL (RBL) bash script checker

So you want to regularly check your IP(s) if they got listed on one of the many (800+ to be exact)  public blacklists (also known as DNSBL or RBL)?

Bellow, you can find a bash script that will make your life much easier. You can also make a cronjob that sends you an email with the results or simply display the results with PHP.

#!/bin/sh
# Check if an IP address is listed on one of the following blacklists
# The format is chosen to make it easy to add or delete
# The shell will strip multiple whitespace
# Last updated on 20.02.2019 @ slurp-ramen.com

Have questions regarding e-mail blacklists and how they work? Well, when I have more time I will surely post about it but for now, you may just leave a comment below and I will reply when I can.
