IP Address: 2a01:111:f403:2407::622 ⚠ IP Confounder

The host is operated by ORG-MA42-RIPE and geolocates to Boydton, 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. Microsoft Exchange Online Protection (EOP) and Office 365 relay addresses appear in DMARC reports for mail routed through Microsoft's filtering infrastructure. Ensure your SPF record includes Microsoft's published mail server ranges.

IP Confounder: Microsoft 365 Exchange Online Protection (EOP)

Exchange Online Protection (EOP) is a cloud-based email filtering service included with all Microsoft 365 subscriptions to protect against spam, malware, and phishing attacks. It automatically secures mailboxes by filtering incoming and outgoing messages in real-time using anti-spam, anti-malware, and content filters. During periods of active campaign activity, these can largely be ignored (esp. when recipients are on Exchange). However, forged emails have been observed from Microsoft infrastructure that have this signature too.
