Created attachment 873135 [details]
archive of /etc/postfix in case the contents post package installation

After updating my tumbleweed system today to postfix-3.8.5-2.1.x86_64, postfix
no longer starts. To ensure it wasn't something I had done, I moved the whole
of /etc/postfix aside, and reinstalled the package. The daemon failed in the
same way with fresh default configurations:

hostnamectl reports a static hostname of my FQDN, with a pretty hostname of
just the hostname component. I have had this configuration for years.

I have attached /etc/postfix in case that should be useful (ie in case some
postinst scripts are mangling it). The directory was absent prior to
reinstalling the package, and I made no changes.
