I've configured Feedback Loop (FBL) abuse reports for newsletter on https://returnpath.com to track users, who mark my emails as "Spam" and unsubscribe them on my end. The problem is, I couldn't figure out how to read these reports.
Here is an example of abuse report message headers that I receive from Return Path.
Content-Disposition: inline Content-Transfer-Encoding: 8bit Content-Type: message/feedback-report Feedback-Type: abuse User-Agent: ReturnPathFBL/2.0 Version: 1 Arrival-Date: Thu, 21 Feb 2019 15:34:23 +0000 Reported-Domain: psrp.example.com Subscription-Link: https://fbl.returnpath.net/manage/subscriptions/xxxx Original-Rcpt-To: email@example.com Original-Mail-From: firstname.lastname@example.org Source-Ip: x.x.x.x Source: Mail.Ru Abuse-Type: complaint
As I understand, the complaint came from email@example.com
The problem is, I never sent my newsletter to this email. How could possibly complaint come from there, or am I reading it wrong?
