I first saw this strategy some couple of years ago. I'm pretty sure that it was designed to evade the old static word-list filters, not particularly 'learning' filters. > I would like to know if there is a package in stable that could > effectively handle this newer spam format (not likely is my guess)?

Lacking any specialized solution, I suspect that Bogofilter will eventually handle them pretty well if you just keep training it. You'll end up with a huge spamlist database, but the broken-up word fragments will end up with a spamicity rating very close to 1, won't they? Because they'll never occur in a legitimate mail...
