Error in Ghost Setup - Githubissues

With a fresh docker build from dockerfiles/ghost, I get the following error when I try to setup the blog, causing the docker container to crash.

/ghost/core/server/mail.js:95
                if (data.error.errno === 'ENOTFOUND') {
                              ^
