Shame on you, stupid spammers.. Sh4meful  DMARC Spoof Detection 🦋 Bluesky

IP Address: 107.173.177.172

The data here is from DMARC analysis for domains I administer, drawn from a larger dataset (comprising millions of authentication records and messages). These entries are from email attempts that failed both SPF and DKIM (and there are often alignment issues - hidden here). In many cases, these failures indicate unauthorized use of the domain name, and are commonly associated with spoofing, phishing, or other abusive mail activity.
