If I have a keyword like R0lGODdhDgKAAYcAAP is it supposed to find it even if its in the middle of the Base-64 string as below? I did this to try and stop a ton of stock spam thats getting by and its Base-64 encoded. I can'r use the builtin ini setting because it catches too many pictures of grandma and such. Using the filter with a partial of the Base-64 works occasionaly, but I still get a lot through and I checked to make sure that is not whitelisted. Should this work OK consitently or does SFI need to see a delimeter somewhere. Thanks!

Webguys, The built in base64 filter doesn't effect correct base64 images. It is designed to batch plain text pretending to be images so Grandma should be ok. |

Benny, There is an INI setting "FilterBase64html=1". This filters "Content-Transfer-Encoding=base64 and Content-Type=text/html/plain" but doesn't touch normal image encoding. |
