“Truncate” is an rfc5782 compliant DNSBL listing IP addresses that produce exclusively email containing spam, scams, viruses, or other malware based on statistics in the global GBUdb network. Maintenance of this list is completely automated and there are no provisions for the manual addition or removal of entries.
IPs are added to this list when substantially all recorded events for a given IPv4 address indicate the message content was spam, scam, virus, or other malware. IPs can be added to this list within 10 minutes or less of an outbreak. The data is collected in real-time and the zone is updated once every 10 minutes.
