Oops - I found the link. Let's see what happens when I try it on an ancient PC. http://www.win.tue.nl/~martijna/Debianstuff/ - just starting it up was slow - and moved a lot to sawp. Hmmmm, checking df I think I need at least 64 Meg memory to do Exim4, ClamAV and SpamD. Now to wait for a Spam. Shouldn't take long.
