Hello, kind folks!
Are there any helpful souls from the Cisco Talos IP & Domain Reputation team lurking, who could help me out by answering a few questions regarding fluctuating SMTP server IP reputation? Some public sector entities in my neck of the woods are using Talos to evaluate incoming e-mail, and lately we have periodically had to worry about people not being able to contact police, ambulance services, some hospitals or even their unemployment office via e-mail, because our SMTP IP reputation at Talos has suddenly gone from Neutral to Poor. Unfortunately neither Talos general support channels nor the entities that use Talos have been unable to pinpoint a specific issue for us, that would allow for us to account for these anomalies. Maybe there is someone out there with more intimate access to Talos’s evaluation data and can shine some light on why “the computer says no”. Any help would be appreciated. With best regards, Ardi Jürgens
