Hi,
be something to be gained by running the OCR scan from mimdefang? The idea would be to run the scan, and if sufficient text results (I'd hesitate to suggest that a quick spelling scan would be run on the result, but that is a possibility) that this text is written by MdF into a new text attachment. The message is then reformulated and passed to Spamassassin. The advantage of this approach is that SA (and rules du jour) already have rules for catching things like pharma and stock scam e-mail, so the normal scoring should catch these
Hmm, the SA and rules du jour stock and obfu rules suck ;-) Beside that, I also match some words which are 100% legitimate. And the OCR words are often truncated so one must match those too.
things. Also this approach would work on versions of SA prior to 3.1.1. There is a design decision as to whether the OCR'd text attachment should remain in the message and then be delivered to the user, or whether it would only be kept if SA scores the message as spam.
If you add the OCR'd text attachment to the message you'll have to resend the whole message. Not a good idea IMHO.
