About SpamRats RATS-Dyna

RATS-Dyna flags IPs whose PTR record follows a dynamic/auto-generated pattern — the kind ISPs give home connections. A real mail server should have clean, static reverse DNS.

Why an IP gets listed

  • The PTR record contains the IP address, or words like “dynamic”, “dhcp”, “pool”, “dsl”, “cable”.

How to delist from SpamRats RATS-Dyna

  1. 1Change the reverse DNS to a proper static mail-server name (your ISP/host sets PTR).
  2. 2Confirm forward and reverse DNS match.
  3. 3Remove the IP via the SpamRats lookup page once rDNS is corrected.

Before you request removal: fix the root cause first — delisting while the problem persists almost always leads to a fast re-listing. Confirm the IP has valid reverse DNS, and that your SPF, DKIM and DMARC are in order.
