I notice all of my newest spam that doesn't get caught has either .gif or .jpg attachments.
Yeah, after about 6 months worth of training and such, it's still coming through. Spam setting is 66 and 20.

So, I would like to add like 1 or 2 points to all incoming e-mail with each of those two attachments.
After spending hours looking at postfix, amavis-new and dspam config files and their respective website faq's, is it even possible to do this and if so, which one would be the best place to for me to do this? Anyone else do this?

Thanks in advance. :-)
