Thanks for going through this with me. It seems that you have two problems:
1) You're asked to accept the changelogs before the upgrade proceeds. 2) You're prompted by debconf for postfix configuration options before the upgrade proceeds. The first is due to your decision to install apt-listchanges, its local configuration on your system, and possibly bug 788519. Try running "sudo dpkg-reconfigure apt-listchanges" to see if it has any debconf options to stop it prompting you, see the bug for a workaround, or just remove the apt-listchanges package if you don't need it. The second is the standard debconf prompt. See debconf documentation for details on this. Based on the debconf settings on your system, it looks like the question wasn't answered before and so it is asking it again. This is expected behaviour. To suppress the prompt entirely, try setting DEBIAN_FRONTEND=noninteractive. For the first issue, please refer to bug 788519, or file a new bug against apt-listchanges if you think you have a different issue with it. The second issue is not a bug in the postfix package, so I'm marking this bug as Invalid in postfix.
