Got bitten by this bug when testing the server using telnet.
See https://bugs.launchpad.net/ubuntu/+source/opendmarc/+bug/1574562
I fixed this on my (stripped down) version by using ubuntu 16.04 LTS which has newer opendmarc.
Upgrading to 16.04 could be a nice PR 馃槃
@42wim do you want to participate?
Sorry, I don't have the time right now, maybe in a couple of weeks
It is merged and it state that it fixed this issue.
Closing it.
