Installation

Download the tarball (see How to Obtain) to your spamassassin configuration directory and unpack it to /etc/mail/spamassassin/ (You may choose another location but all necessary adjustments to the configuration file are up to you then). Open FuzzyOcr.cf and extend the wordlist as you wish. If you have the helper binaries in a different location than the default in the config file specifies, then change these to the correct path.

The scoring is dynamic, more word matches lead to a higher score. The scoring is done as soon as focr_counts_required matches were found. It scores exactly focr_base_score points then. For every additional match, it scores additionally focr_add_score points.

...
