About this Blacklist

My systems gather information about SMTP clients or contacts in general. I collect this information in a database and score these clients based on their behaviour over the last 180 days and their name. The name is used if I know it designates a port scanner, for instance.

Every network on this list has demonstrated only bad behaviour, with no positive cases observed. If you want to be removed from this list, send me a "good" email from an IP address within these networks and repeat that every 180 days.

The list consists of CSV data (colon-separated values) compressed with zstd and will be updated every 24 hours. (Please note that since there is only one field, there will be no separators.)

The fields are:

• Network that is suspicious.
