Analysis
This IP is classified as a confounder: Kaseya/Inky. Failures observed from this source are expected artifacts of legitimate mail-handling behavior, typically email forwarding or mailing-list processing, and do not indicate spoofing attempts.
The host is operated by Amazon Technologies Inc and geolocates to Columbus, United States. Its presence in DMARC aggregate reports is an artifact of how forwarded mail interacts with SPF and DKIM authentication, not a sign of abuse originating from this address.
Administrators observing this IP in their DMARC aggregate reports should not block or treat it as hostile. Consult the documentation for this mail-handling service to determine whether your SPF record should be updated to include its relay addresses, or whether ARC sealing is appropriate for your configuration.
