Does forwarding mailers affect DMARC alignment and how to mitigate?
Yes—forwarding can and often does disrupt DMARC alignment by breaking SPF at the forwarder and sometimes DKIM when headers or body are modified; the practical mitigations are SRS for SPF, ARC for alignment preservation, resilient DKIM practices (relaxed canonicalization and strategic re-signing), and DMARC policy/report tuning backed by continuous monitoring. Email authentication hinges on three…

This poses a risk of data exposure, combined…
