I've been playing with FuzzyOcr and FacileOCR in spamassassin (current trunk). Both plugins are built and installed, and test properly; however, I'm not sure spamassassin is actually using them in routine mail scanning. Basically, after 2-3 days running (ca 1000 spams) I've yet to see a spamd log line that contains something like fuzzy or ocr. Nor have I seen the like in any of the spamassassin header lines.
Finally, I'm using FuzzyOcr with type 2 hashing. This will create several databases (as they were when I ran an explicit test). However, after deleting them and restarting spamd they have not been recreated. Doesn't look like the tests are being triggered. Anybody know why? David
