What it lists
Dyna is part of Spamrats' RATS suite; it identifies IPs whose rDNS pattern suggests a dynamic / consumer allocation that should not deliver mail directly.
Who gets listed
IPs with rDNS that matches dynamic-IP naming patterns.
Reputation impact
Low when other authentication is strong; can affect deliverability at smaller MTAs.
