Way To Block A Specific Word From Image

["KADAM, SIDDHESH" <si...@netcore.co.in>]

Hi Folks,

Is there any possibilities of blocking a specific word from an image 
using SpamAssassin ?

Spin up a vagrant instance and test.

I recommend using the scan size to 1024. For I found anything less was 
getting missed.

# Increase scanning size of FuzzyOCR to 1024
sed -i 's/#focr_max_height 800/focr_max_height 1024/' 
/etc/spamassassin/FuzzyOcr.cf

sed -i 's/#focr_max_width 800/focr_max_width 1024/' 
/etc/spamassassin/FuzzyOcr.cf

I would like to add, I don't use FuzzyOCR in production.
In my teams testing, we found the signatures of Sanesecurity (along with 
KAM) were sufficient enough.

If I can ask. Can you share your feedback / experience with the 
community, in the spam you analyzing?

HTH

I think FuzzyOCR plugin can do something similar - OCR scan the image and
blacklist on words.
