I don't know much about DMARC but apparently it's the third magical thing (after SPF and DKIM) that stops people from marking your e-mails as spam.

@edmund-huber could you provision a TXT record at _dmarc.darwin.network, with contents:

v=DMARC1; p=none; sp=none; pct=100; rua=mailto:admin@darwin.network
