How it works

This plugin checks for specific keywords in image/gif 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. The mail itself only random text and random html, without any URL's or identifiable information.

You will need giftopnm and gocr installed.
