Apache::AntiSpam::HTMLEncode is a subclass of Apache::AntiSpam, filter module to prevent e-mail addresses exposed as is on web pages. This module encodes e-mail addresses with HTML.

For example, miyagawa@cpan.org will be filtered to miyagawa@cpan.or&#103.

This won't affect anything on your favourite browsers, but spammers with crawling-robot plus pattern matching technique won't be able to extract addresses from this kind of format.

This module is Filter aware, meaning that it can work within Apache::Filter framework without modification.

The idea to encode E-mail address with HTML is stolen from http://perlmonks.org/?node_id=89810
