The setup script of postfix /usr/sbin/config.postfix is very old and very often causes problems. We need to discuss whether we need such a script at all. Postfix is extremely complex. Configuring everything via scripts and sysconfig variables is impossible and ultimately does not make things any easier. It is difficult to decide what should be configurable in this way and what should not. Since openSUSE/SLES 16.0, there is no longer a graphical tool that would really simplify configuration. Furthermore, the basic configuration of Postfix is a one-time task that requires a great deal of expertise. During operation, only the postmaps need to be maintained.
