OTOH -- if relying on people to abide by list policy is the cornerstone of your anti-spam policy, I suggest you look for something a little more robust. I'm sure for a users' list such as debian-kde, many participants won't have even read it. And a NOSPAM-munged From: address isn't the best strategy either, since such addresses are expliclty designed so that humans *can* accurately reply to them whilst machines can't (though of course machines probably can these days as well, but that's another matter). In particular, if not being CCed is such an absolutely critical matter for you, it's possibly worth a one-line "Do not CC me on list replies!" in your .sig, just to hammer the point home. But I tell you what, here's a deal. You thank me for the immense number of hours that I have spent packaging KDE for you for free over the last few years, and I'll apologise for that CC. Ben.
