I've recently setup a mail server, which will be handling email for multiple people and domains. Appropriate SPF, DKIM, DMARC and ADSP records have been added, yet I'm getting something confusing:
Authentication-Results: mx.google.com; spf=pass (google.com: domain of email@example.com designates 188.8.131.52 as permitted sender) firstname.lastname@example.org; dmarc=pass (p=QUARANTINE dis=NONE) header.from=redacted.com Authentication-Results: de.mx.redacted.com; dmarc=fail header.from=redacted.com
As you can see I'm getting TWO Authentication-Results headers, the latter signifying a fail for some reason. My records are in order, as far as I'm aware:
SPF: "v=spf1 mx a ptr include:_spf.redacted.com ~all" SPF: "v=spf1 ip4:184.108.40.206/32 ip4:10.10.33.109/32 ip6:2c03:10e0:3:a0::1bc9:2001/64 ~all" DMARC: "v=DMARC1; p=quarantine; pct=100; rua=mailto:email@example.com; firstname.lastname@example.org; fo=1; aspf=r; adkim=r" ADSP: "dkim=all"
