@TecDeveloper: Good idea, i changed the form to post.
@msl-durgesh Maybe this could help or inspire (https://dnsbl.tebe.ch, https://github.com/tbreuss/dns-blacklist-check)
Thanks @istiak101. I will go through your referencies and remove the UceProect RBLs.
Be aware: zen.spamhaus.org marks a lot of private ip adresses, which don't send out spam and fill out regular forms.
I would recommend using primarily uceprotect level 1, 2 and also 3.

you do know that uceprotect is even worst than spamhaus.
At least spamhaus has a usable delisting process and keeps its listings up to date.
Not to mention uceprotect charges for removal even if it is not your problem.
Hello.
The script works ok on A records, but actually due to my type of work i do not use A records but we add Name Servers. Can you please help me on how to change the script to work on NS.
Regards,
Mond
It works perfectly. Grete work
Thank You!
I think you must change the system to ‘post’. Because anyone can see the users IP address from the address bar and this is quite dangerous
