Fuzzy OCR Support - block those image spams!
Hello fellow Piratefishers!
I know that on-going development with the Piratefish has been slow-going lately, so I'm sending this message out today to inform you of a new update now available for your Piratefish Anti-Spam Gateway.
This new update adds Fuzzy OCR capabilities to your Piratefish - so no, when an image spam comes into your Piratefish, the Piratefish will decode the image, and then run an Optical Character Recognition scan on the image, looking for words that are a near match to a list of words you can customize.
I added this change to my Piratefish test system a few months ago - when it was first introduced no image spams were getting through at all. Now, a few months later, only very few image spams get through now. Seems that the an additional payload of gibberish can help image spams get through now, hopefully SpamAssassin will figure out how to detect that soon.
This update is a little unorthodox, requiring the user to use Debian Unstable sources to install the latest version of SpamAssassin, but the trouble is worth it.
If you're running with a registered version of Piratefish 2.3, this upgrade is free - just visit the support page in your registration email.
This update is not available for users of the Piratefish 1.0 system.
Happy Holidays!
