I did not do this myself, but I think the whole line should be a regular expression. So it will be something like:
'[a-zA-Z0-9_]\.domain\.de': '127.0.0.1:8085',
Pay attention to the screening of points. In fact, it would be easier (although perhaps not so safe) if this format is correct:
'.*\.domain\.de': '127.0.0.1:8085',
Or even:
'\w*\.domain\.de': '127.0.0.1:8085',
