Overview
Singular TTK is maintained by the Budapest University of Technology and Economics (BME) network center. It's a small, academic-run blacklist that primarily serves the Hungarian academic network.
How It Works
The list is based on spam data collected from the Hungarian academic network. When an IP sends spam to mailboxes on these networks, it gets logged and listed.
How to Get Delisted
As an academic operation, there's no dedicated self-service removal tool. Listings typically expire automatically after a period.
This blacklist does not support manual removal. Listings expire automatically once the underlying issue is resolved.
