fuzzyocr ソースパッケージをダウンロード:
This Spamassassin plugin checks for specific keywords in image/gif, image/jpeg or image/png attachments, using gocr (an optical character recognition program). This plugin can be used to detect spam that puts all the real spam content in an attached image, while the mail itself is only random text and random html, without any URL's or identifiable information. Additionally to the normal OcrPlugin, it can do approximate matches on words, so errors in recognition or attempts to obfuscate the text inside the image will not cause the detection to fail.
This is a development version from SVN. Currently, this SVN version is the only one that works with spamassassin 3.2.
