Just curious, but I can't tell the connection to the lines you quoted. It was about setting up a filter that keeps certain messages on the server instead of downloading them.

Personally, I liked Spambayes a lot, but yours looks interesting as well. I would try it, but I've already switched to Thunderbird, which has far more problems in my view than either Outlook programs. It's really ticking me off at the moment. Its spam filter is absolutely horrible to use.
