We've just implemented the FuzzyOCR plugin for SA, which uses gocr
under the covers. It's catching 100% of the current wave of image spam
with no FPs reported yet. Very impressed.
Since the OCR is farly expensive I might look at pulling out the SA
plugin bits and implementing the guts as a perl module to call
directly from Exim (before SA), where I can be a bit more choosy about
which attachments I choose to process.
