Keeping an eye on your DMARC reports is one of the best email authentication

practices. Email environments aren’t set in stone, so you must also adjust the

configurations in time. Depending on your organization’s needs, new sending sources

might be added or removed, and the new ones will need configuring.

In addition to new sources, it’s always good to review email sending patterns,

deliverability issues, and changes in the system. Staying alert always helps keep the

infrastructure up-to-date, register occasional phishing attempts, or manage alerts and

anomalies.
