The Why

There are various ways that ISP’s choose to defend their users against Spam Abuse, Scams, Phish and Abuse.

Many ISP’s open your emails and read the words inside to judge whether you are allowed to receive that email or not, scanning for virus or dangerous content in an email was simply extended to invade the privacy of all people without much fanfare, objection or  even notice.

Instead of punishing the sender for sending spam abuse, phish, virus in fact the present operating philosophy on the Internet is to allow the bad actors to continue sending abuse.

Spam is a great excuse to inspect all incoming and outgoing email content and the majority of email servers automatically read the content of all emails so that a program can decide if you may receive that email or not. The same filters and programs are also used for other purposes.

  1. Not properly maintained by the IP operator, 
  2. Continues sending spam abuse, phish,virus or scams
  3. Not real email servers.


Why is my email blocked?  –  The philosophy of dnsbl.ascams.com is to block the bad senders.

Some ISP’s and ESP’s defend against spam blocks by adding good customers, well known brands and other respected people to the pool of bad senders. These providers always promise to investigate and apply their AUP’s, but their abuse is ongoing and does not stop.
