Disabling FuzzyOCR module for Spamassassin
Added about 5 years ago
FuzzyOCR is a SpamAssassin module which allows text detection inside pictures.
Sometimes FuzzyOCR is behaving badly, and needs to be deactivated during the time for analyzing.
Example of log content /var/mailcleaner/log/mailscanner/spamd.log:
warn: FuzzyOcr: Skipping scanset because of errors, trying next... error: FuzzyOcr: Error running preprocessor(pamthreshold): pamthreshold -simple -threshold 0.5 warn: FuzzyOcr: Errors in Scanset "ocrad-decolorize" warn: FuzzyOcr: Return code: 2048, Error: save_execute: failed to exec pamthreshold -simple -threshold 0.5: at /usr/mailcleaner/share/spamassassin/plugins/FuzzyOcr/Misc.pm line 189.
To disable FuzzyOCR in the web interface, go to: Configuration > Anti-spam > SpamC and uncheck the Enable text recognition in images option.
Next go to Monitoring > Status and restart the service Filtering engine.
If the problem is persisting: restart the
mailscanner service on the MailCleaner host:
