Thanks All,
I fully accept that exim is as it is, and being an
(instrumentation-)developer
myself it's easy to see how we got here. As stated in my very first post,
I did make it all work by using "proper" ;-) entries in /etc/hosts,
hostname and mailname. This being my first email server installation,
I was simply surprised and wanted to understand the background.
So, thanks again for your explanations and your patience
Klaus
