DESCRIPTION

Apache::AntiSpam is a filter module to prevent e-mail addresses exposed as is on web pages. The way to hide addresses from spammers are implemented in each of Apache::Antispam::* subclasses.

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

SUBCLASSING

Here is how to make your own filter.

Declare your class
Inherit from Apache::AntiSpam
define antispamize() method
That's all. Template of antispamize() method will be like this:

      sub antispamize {
          my($class, $email, $orig) = @_;
          # do some stuff..
          return $orig;
      }

where "$class" is your class, "$email" is an instance of Mail::Address, and "$orig" is an original e-mail address string. See the Email::Find manpage for details.

TODO

• remove mailto: tags using HTML::Parser.

ACKNOWLEDGEMENTS

The idea of this module is stolen from Apache::AddrMunge by Mark J Dominus. See http://perl.plover.com/AddrMunge/ for details.

Many thanks to Michael G. Schwern for kindly improving the matching speed of Email::Find.
