I need to install Postfix on a fresh Ubuntu box on first boot, but the interactive configuration screen that the installer presents to you isn't scriptable. When my startup script attempts the following:
apt-get -y install postfix
the init script hangs. If I run it by hand, I'm presented with a "dialog" screen from the whiptail command.
Is there a way for me to force a particular option from the command-line, or tell the Postfix installer that I don't want it to give me any configuration at all? I'm generating my own main.cf file anyway, and don't need Ubuntu's helper screen.

should do the trick. You may want to lay down working config files on the system after you run that, though.
