Hi Klaus, I think the culprit is the misconfigured `search .` domain in /etc/resolv.conf. However that's not a Docker (image) default: it's just inherited by the host system. Can you please verify this is the case, try fixing it in the host system and try the postfix install in docker once again? If it still doesn't work, can you please share the /etc/resolv.conf of the host system?
I'm setting the status of this report to Incomplete for the moment. Please change it to Invalid if you end up finding this is just a configuration issue, otherwise comment back, change it back to New and we'll look at it again.
