Title:
  Wrong FQDN after disconnected CD Install of precise beta1 - package
  postfix 2.8.7-1ubuntu2 failed to install/upgrade

Status in “netcfg” package in Ubuntu:
  Fix Released

Bug description:
  Summary: postfix fails to install due to wrong FQDN set during
  disconnect CD installation of precise beta1

  Hi all,

  last night I've reinstalled my laptop using the ubuntu-12.04-beta1
  -alternate-amd64.iso, during the installation I've chosen to configure
  my network later (laptop; no wireless at the time) and it seems that
  this caused the installer to generate a "<myhostname>.(null)" entry
  for /etc/hosts.

  Postfix is now set up with a default configuration.  If you need to make 
  changes, edit
  /etc/postfix/main.cf (and others) as needed.  To view Postfix configuration
  values, see postconf(1).

  After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.
