This is a problem with some BIOSes AFAIK. Type:-
# cat /proc/meminfo
for memory information.
If you have more memory than it says, at the boot: prompt type:-
boot: linux mem=128M
for example. To make this permanent, add the following line to
and then type "lilo". When you reboot it should pick up all
the memory. Replace 128M with your memory size too!

Type "df" and it will tell you.
My mail config "just worked" so I couldnt help you with that! :p
Hope this helps,
