Warning: if you use this script to install Postfix locally,
this script will replace existing sendmail or Postfix programs.
Make backups if you want to be able to recover.
Before installing files, this script prompts you for some
definitions. Most definitions will be remembered, so you have
to specify them only once. All definitions should have a
reasonable default value.
