ASPEWS, also known as Another Spam Prevention Early Warning System, is a list of areas on the Internet that several system administrators, ISP postmasters, and other service providers have assembled and utilize to block email and in some instances, all network traffic from. The ASPEWS list is used to block spammers and spam operators once they have been identified.
Aspews Reports Subnets
Subnet-based Blacklists are used to reject email from entire ranges of IP Addresses, i.e. providers that are hosting companies sending spam, as well as single IP Addresses that may fall in that range of IP Address.
Aspews Automatically Delists Entries
This blacklist does not offer any form of manual request to delist. Your IP Address will either automatically expire from listing after a given timeframe, or after time expires from the last receipt of spam into their spamtraps from your IP Address.
