A few times I needed to do something like the OP in this thread, when I was still in the mbox camp. I didn't know any better so I used formail from the procmail package -- I think it's the `-s` or maybe `-S` option. *Not one time* it went without a problem -- in the better case the problem was just not getting the correct result out of the split operation, but the worse case of losing mail also happened. After the last of these occassions, must be about 10 years ago, I switched to maildirs for good. -- Ian
