I've recently set up a DMARC record for my domain and now I'm receiving email abuse reports from hotmail.com that state:
This is an email abuse report for an email message received from IP 104.47.126.207 on Sun, 14 Feb 2016 07:20:43 -0800. The message below did not meet the sending domain's authentication policy.
104.47.126.207 resolves to mail-pu1apc01hn0248.outbound.protection.outlook.com
My SPF record is
v=spf1 ip4:{my MX IP} -all
So what does it mean? Does Hotmail try to relay an E-mail in some way? Should I worry about it?
It also states that both SPF and DKIM checks have failed
Authentication-Results: hotmail.com; spf=fail (sender IP is 104.47.126.207; identity alignment result is pass and alignment mode is relaxed) [email protected]; dkim=fail (identity alignment result is pass and alignment mode is relaxed) header.d=domain.com; x-hmca=fail [email protected]
UPDATE
An e-mail attached to the abuse report is an automated notification to the customer that MUST be sent from my server.
UPDATE
These are the Received headers from the attached e-mail
