Subject RE: Suggest OCR plugin on Spamassassin 3.3.1 for image spam
Date Thu, 21 Jul 2011 06:53:02 GMT

The current functionality requires me to receive mails that contains image and process them.

So I want a good tool to deal with image spam.

Please suggest some.

Image spam was a huge deal when it first came out, and there were 
several sources scrambling to offer a solution, including resources to 
involve Bayes on the decoded text.  Those worked well enough to deter, 
for the time-being anyway, that method of spamming.

That said, while I agree with your sentiment toward inline images and 
HTML mail in general, they are a common business practice and many folks 
simply can't use the outright block method.

At my last job, I eventually found that image-spam dropped to such a 
significant low that I didn't need OCR anymore but was still required to 
allow inline images through.
