Block spam at smtp time, but then still forward to users spam box

Hi all, I was looking through a few lists of RBLs and I’m not finding quite what I want. I have quite a bit of my spam blocking working fairly well, but I’m seeing quite a bit of “snowshoe spam” from a few providers. Rather than look up their netblocks and outright block them, I’d like to incor
