For an organization migrating from Exchange to Google Workspace, what must be ensured regarding domain settings?

When migrating from Exchange to Google Workspace, it’s essential to ensure that SPF, DKIM, and DMARC are correctly configured. These settings are critical for securing email communications and preventing spoofing and phishing attacks.

SPF (Sender Policy Framework) is a protocol that helps to specify which mail servers are authorized to send emails on behalf of a domain. This helps protect against unauthorized use of the domain in email communications.

DKIM (DomainKeys Identified Mail) adds a digital signature to the emails sent from the domain, which allows the receiving mail server to verify that an email is indeed from the specified sender and has not been altered in transit.

DMARC (Domain-based Message Authentication, Reporting, and Conformance) builds on SPF and DKIM by allowing domain owners to publish policies regarding how email receivers should handle emails that fail SPF or DKIM checks. This adds an additional layer of security and reporting, helping organizations monitor and mitigate issues related to fraudulent emails.

Configuring these settings correctly is fundamental during the migration to ensure that the organization's email reputation is maintained and that legitimate communications are not incorrectly flagged or rejected. This step enhances email deliverability and protects the organization's identity online, which is particularly crucial when transitioning to a new email platform like Google Workspace.
