according to the spec it's
ENV <key>=<value>
does it work without the equal too?

Both are working. The current Dockerfile use space, so let's keep it consistent with the style already used.


ENV PATH=$PATH:./node_modules/.bin HOME=${MTA_USER_HOME}

on the image i used i do not have this path entry:

mta@63fceb6d640d:~$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

is it intended that the root user has the home of mta?

root@b40df04c7063:/project# id
uid=0(root) gid=0(root) groups=0(root)
root@b40df04c7063:/project# echo $HOME
/home/mta

It's not intended and a genuine security bug, and as well as the HOME env variable redefinition.
The PATH env variable mangling is buggy as hell in that Dockerfile. I plan to fix it but in another PR.

Thanks.
