Tuesday I installed FuzzyOcrPlugin because there were quite a lot of spam emails coming through my spamassassin spam filter lately. It appeared to be mostly messages containing only an image with spam text on it which could not be processed.
There were some minor issues getting this plugin to work. Had to install gocr, libungif-bin and some other dependencies. Since the plugin is active there havn’t been any spam message that sneaked through. So I am very pleased with the result, hope it stays like this for some time.
