Apache::AntiSpam::SpamTrap is a subclass of Apache::AntiSpam, filter module to prevent e-mail addresses exposed as is on web pages. This module adds a Blowfish encrypted string suffix to the local-part of e-mail addresses. This string contains a timestamp and the IP address of the remote host. This enables you to identify a spammer's address harvester by its IP address and take steps to prosecute him.
The encryption prevents faking and may help in a prosecuting attemp.
For example, <apleiner@cpan.org> will be filtered to <apleiner-78c1ed6da0322b3a@cpan.org>.
This module is Filter aware, meaning that it can work within Apache::Filter framework without modification.
This work is based on the Apache::AntiSpam::* modules provided by Tatsuhiko Miyagawa <miyagawa@bulknews.net>. The idea is taken from Daniel A. Rehbein (http://daniel.rehbein.net/).
