They also provide visibility into your email ecosystem through detailed aggregate reports.&nbsp;<\/p>\n<p>DMARC aggregate reports don&#8217;t contain sensitive message content, but they offer an overview of sent emails claiming to be from your domain. They show:<\/p>\n<ul>\n<li>Whether emails passed DMARC authentication.<\/li>\n<li>Which servers sent them according to source IP\/sending domain.<\/li>\n<li>What actions did receiving mail servers take based on your DMARC policy.<\/li>\n<\/ul>\n<p>These reports can help you determine whether your DMARC setup is effective, identify legitimate email sources that may be misconfigured, and detect potential unauthorized use of your domain. &nbsp;<\/p>\n\n<div class=\"container pt-3 pb-5\">\n\t<div class=\"row blog-cta-blue  p-4\">\n\t\t<div class=\"col-12 mx-auto\">\n\t\t\t<div class=\"row d-flex align-items-center\">\n\t\t\t<div class=\"col-lg-6 col-12\">\n\t\t\t\t<p class=\"bold fs-4\">Unlock 2026 inbox benchmarks now<\/p>\n\t\t\t\t<p>Download Validity\u2019s 2026 Email Deliverability Benchmark Report and learn how your inbox placement compares before your next send.<\/p>\n\t\t\t\t<button class=\"button-blue arrow\"><a rel=\"noopener\" target=\"_blank\" href=\"https:\/\/www.validity.com\/resource-center\/2026-email-deliverability-benchmark-report\/\" class=\"text-white text-decoration-none\">Get the report<\/a><\/button>\n\t\t\t<\/div><!--col-6-->\n\t\t\t<div class=\"col-6 d-none d-lg-block\">\n\t\t\t\t<img decoding=\"async\" src=\"https:\/\/www.litmus.com\/wp-content\/uploads\/2024\/12\/blog-cta-12172024.svg\" width=\"208\" height=\"171\" alt=\"\">\n\t\t\t<\/div><!--col-6-->\n\t\t\t<\/div> <!--row-->\n\t\t<\/div><!--col-12-->\n\t<\/div><!--row-->\n<\/div><!--container-->\n\t\n\t\t\n\t\n\t\n\t\n\n<h2 id=\"important\">The most important DMARC information<\/h2>\n<p>Here&#8217;s what to prioritize:<\/p>\n<ol>\n<li><strong>Failing email authentication from legitimate sources: <\/strong>Look for emails that are failing DMARC authentication but are coming from IP addresses that belong to your authorized email senders. These suggest a misconfiguration in your Sender Policy Framework (SPF) or DomainKeys Identified Mail (DKIM) records, which can lead to <a rel=\"noopener\" href=\"https:\/\/www.litmus.com\/blog\/how-your-content-could-trigger-the-spam-filter\">legitimate emails being sent to spam<\/a> or blocked.&nbsp;<\/li>\n<li><strong>Unfamiliar sending IPs:<\/strong> Monitor unfamiliar or unexpected IP addresses that attempt to send emails claiming to be from your domain, especially if those emails fail authentication. Flag them quickly as they indicate spoofing or phishing attempts.<\/li>\n<li><strong>Policy actions:<\/strong> Review the DMARC policy actions taken by receiving servers, such as quarantine or rejection, to confirm whether your DMARC policy is being enforced as intended.<\/li>\n<\/ol>\n<h2 id=\"data\">What to do with DMARC data<\/h2>\n<p>Here&#8217;s what to do next, depending on what the reports show:<\/p>\n<ul>\n<li><strong>Legitimate emails are failing authentication:<\/strong> Investigate the specific email sending platforms or servers. You&#8217;ll need to check their configurations to ensure they&#8217;re correctly set up to authenticate emails from your domain. This might involve updating your SPF or DKIM records in your domain&#8217;s DNS settings. Resolve these issues to <a rel=\"noopener\" href=\"https:\/\/www.litmus.com\/blog\/why-email-deliverability-matters\">enhance your email deliverability<\/a>.<\/li>\n<li><strong>Unauthorized or suspicious senders:<\/strong> If the reports highlight unfamiliar IP addresses trying to send emails claiming to be from your domain, and these emails are failing authentication, this is where you leverage your DMARC policy. If your policy is set to &ldquo;monitor&rdquo; (p=none), consider moving it to a more enforced state, like &ldquo;quarantine&rdquo; or &ldquo;reject.&rdquo; This policy directs receiving mail servers to send those suspicious emails to spam folders or block them.<\/li>\n<\/ul>\n\n\n\n<div class=\"quote my-5 col-12 blue-quote\" >\n\t\n\t<div class=\"row d-flex align-items-center\">\n\t<div class=\"col-12 col-lg-9\">&#8220;<em><em>Fraudsters have already identified <\/em><em><strong>p=none<\/strong><\/em><em> as a weakness, and they are attacking domains where it has been published.
