You can't just play with localhost names and hope they will work...there's a purpose to it.The loopback interface (lo,127.0.0.1) is bound to locahost as defined in /etc/hosts eg.

127.0.0.1 localhost.localdoamin

and it must exist for proper operations (sendmail for one fails if it's missing)
Just make sure to write the info in my example to /etc/hosts and all should be fine again :) .If you want to define your own hostname then add extra entry to /etc/hosts with ip other than 127.0.0.1... eg.

192.168.0.1 myownhostname.somelocaldomain myboxshortname

Hope this helps.
