Look at your /etc/resolv.conf

It should say something like:

domain inbox.org
nameserver foo
nameserver bar

But in reality, yours probably looks like:

search inbox.org
search org
nameserver foo
nameserver bar

Remove that "search org" line.  (Alternately, you might have a "domain
org" which would be even worse. :-)
