-##### security concerns
+## Setup
-The [german wikipedia tells that there are some security concern with fetchmail](https://de.wikipedia.org/wiki/Fetchmail). If in the future a customer needs to functions of fetchmail, it could be better to write a docker container for [getmail](https://en.wikipedia.org/wiki/Getmail) instead because it should be more secure.
