Tom, Sorry, I don't think Outlook 2007 has that feature (line folding). I did look around for it, but I didn't see anything in the options. If someone knows the trick, let me know. Line wrap is set at 76 characters, but it doesn't seem to do anything when I'm composing a message. In answer to your question, yes, I've tried straight-forward traffic shaping. It only works when both circuits reach saturation of either downstream or upstream channels simultaneously. That is when set to the speed of the circuits combined. When set to the speed of one of the circuits, we're wasting half the bandwidth available to the firewall.
