Record Status:
Expired. The ban on this IP has been lifted and it should no longer appear in our generated block lists.
Reason for Ban:
DMARC Violation
Detailed Reason:
This is a special type of spam classification, in which the offending IP has attempted to send e-mail masquerading as one of our domains. However, the IP violates our DMARC ruleset: it is not one of the IPs listed in the domain's SPF record, nor is the message signed by our designated DKIM key. These IPs are unique in the GPF DNSBL in that the have not directly attacked our servers; rather, it is more of a reputation attack, since the spammer is attempting to send spam in our name. All IPs marked with this reason were reported to us by third-party e-mail providers sending us their DMARC reports.
Additional Comments:
Spammer caught sending mail "from" one of our domains. Caught by Mail.Ru DMARC report. Fails both SPF and DKIM tests.
