Sendmail just worked for light use on a 486 with 16 MB. An i386 with 8 MB was more challenging. I only had 32 MB on a Pentium-1 machine. 32 MB still needed swapping, but I turned off swapping when 64 MB RAM became affordable (and used). The 32MB system ran netscape will no obvious problem except that it needed swapping for not much more than netscape. Bruce
