Olduvai is where our lists are. I changed that to our primary MX
because most of the email should go there. We also have better
anti-SPAM and anti-virus software on that box. I'm seeing a lot of
inbound traffic, mostly SPAM. 

We're looking for someone to donate a ProLiant DL380 G4 or G5 so we can
handle more traffic..
