I finally got OpenDMARC working. There are 4 Problems when you first
setup OpenDMARC:

1. the infamous "first header missing" Postfix bug. One has to find a
workaround for that. Should be documented somehwere. 

2. OpenDKIM needs config option "AddAllSignatureResults true". This is
not default and this option is not documented (missing) in OpenDKIMs
sample.conf. Should also be documented in OpenDMARC "first steps".

3. "IgnoreAuthenticatedClients true" is not working because of this bug:

4. This list is not DKIM-safe. (really annoying)

These are too many unknowns for a newcomer to get a proper OpenDKIM
setup. So don't wonder when people get angry.

Mit besten Grüßen
