Ubuntu 18.04.1 droplet trying to get Postfix to work. Cannot get past the message active (exited) from the postfix status command.
Any ideas would be MUCH APPRECIATED.
I have spent days researching and my final brick wall is this Debian bug report:

Message #121 received at 877992@bugs.debian.org (full text, mbox, reply):

I’ve just uploaded an update that changes how the instance generator works.

It seems to help for some people, but not everyone. It should be in 9.4, so
after Debian 9.4 is out, more reports of this problem, with details, would be
useful.

Has anyone found a way to apply this update to 18.04 or a workaround ?? PLEASE
Thank you in anticipation,
