The SpamRATS RATS NoPtr Blacklist is an IP-based blocklist that specifically targets IP addresses that do not have a valid reverse DNS or Pointer (PTR) record. This blacklist (or blocklist) is populated by IPs that exhibit abusive behavior, such as sending an excessive number of connections or attempting to deliver emails to a high volume of invalid user accounts at ISP and Telco mail servers. The lack of a PTR record is a key characteristic for this listing.
According to established best practices for network and email operators, any IP address running a mail server should have a correctly configured PTR record. This record helps identify the party responsible for the mail server. An IP address that is sending a flood of connections without a PTR record is often a strong indicator of a compromised machine or an improperly configured server, which contributes significantly to wasted overhead for receiving mail servers. The RATS NoPtr blacklist contains IPs on networks known to permit outbound traffic on port 25 from addresses lacking a reverse DNS record.

How do I get removed and delisted from SpamRATS RATS NoPtr blacklist?
To get delisted from the SpamRATS RATS NoPtr blacklist, you must first resolve the underlying issue. This blocklist specifically targets IPs without a valid PTR record, so you will only be able to request removal after you have correctly configured the reverse DNS for your IP address. It is important that the PTR record accurately reflects who is responsible for operating the mail server.
- Configure your PTR Record: Ensure your mail server's IP address has a valid PTR record that points to a hostname, for example, mail.yourdomain.com.
- Wait for DNS Propagation: After setting up the PTR record, you must wait for the DNS changes to propagate across the internet. This can take several hours.
- Request Delisting: Once the PTR record is correctly configured and has propagated, you can use the official removal tool on the SpamRATS website to request delisting. If you are unable to remove yourself using the form, you should use their contact form to open a case.
What's the impact of being listed on SpamRATS RATS NoPtr blacklist?
The impact of being listed on the SpamRATS RATS NoPtr blacklist is generally considered low. This specific blacklist is not as widely used as some of the larger, more impactful blocklists in the industry. However, any blacklist inclusion can negatively affect your email deliverability. Mail servers and systems that do use this list will likely reject your emails, leading to bounces and preventing your messages from reaching the inbox. It is always a best practice to resolve any blacklist or blocklist listing promptly to maintain a healthy sender reputation.
