Spam Prevention Early Warning System
Introduction


The **Spam Prevention Early Warning System** (**SPEWS**) was an anonymous service that maintained a list of [IP address](/wiki/IP_address "IP address") ranges belonging to [internet service providers](/wiki/Internet_service_provider "Internet service provider") (ISPs) that host spammers and show little action to prevent their abuse of other [networks](/wiki/Computer_networking "Computer networking")' resources. It could be used by [Internet sites](/wiki/Internet_site "Internet site") as an additional source of information about the senders of unsolicited bulk email, better known as [spam](/wiki/Spam_%28electronic%29 "Spam (electronic)").

The SPEWS database has not been updated since August 24, 2006; dnsbl.com lists its status as dead.[DNSBL lists SPEWS database status as dead](http://www.dnsbl.com/2007/01/spews-current-status.html) A successor, the **Anonymous Postmaster Early Warning System** **(APEWS)**, appeared in January 2007,[APEWS announcement of SPEWS replacement](http://groups.google.com/group/news.admin.net-abuse.blocklisting/msg/b3da24209d8d5319) using similar listing criteria and a nearly identical web page.


Is there a way to combine the features of SPEWS and APEWS into one system?
