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 contect spam content in an attached image, accompanied with . The mail itself only random text and random html (no , without any URL's , etc)or identifiable information.
Note that this is my first SA plugin, so any feedback is welcome. The words checked for are specific for some spam I received a lot of recently. (Hardcoded
TODO: The words check for are now hardcoded in the plugin). This should be a configuration parameter instead.
You will need giftopnm
and gocr
installed.
