What is SpamRATS RATS-NoPtr?
RATS-NoPtr (noptr.spamrats.com) combines two signals: the IP has no PTR record, and it has made excessive connections or tried invalid usernames against SpamRATS' sensors. Google's sender guidelines require valid forward and reverse DNS for sending IPs anyway, so the fix here is one you need regardless of the listing.
Once the PTR record exists and forward-confirms (the hostname resolves back to the IP), the SpamRATS form accepts a removal request; the listing does not clear on the DNS change alone.
How serious is a SpamRATS RATS-NoPtr listing?
Standard: a smaller footprint, used mainly as a scoring signal by some receivers. Fix the cause it points at; weigh the listing itself calmly. The lookup at www.spamrats.com is the reference for whether you are listed today.
Why your IP got listed
What the operator lists: No PTR record plus excessive connections / invalid-user attempts.
How to remove your IP from SpamRATS RATS-NoPtr
- 1
Look the IP up at www.spamrats.com
The operator's own lookup shows whether the IP is listed and, where the list publishes reasons, why. Third-party checkers can lag or misread the zone.
- 2
Fix the cause before you ask
No PTR record plus excessive connections / invalid-user attempts. A removal request while the cause is live is the fastest route to a repeat listing, and repeat listings are slower to clear.
