Below we will discuss in detail one-by-one about SPF, DKIM and DMARC.<\/p>\n<p>What is SPF?<\/p>\n<p>Sender Policy Framework (SPF) is an email authentication method, that is specially designed to know the fraudulent senders addresses during the delivery of the email. SPF allows the domain owners to specify which mail servers are permitted to send emails on behalf of their domain. It reduces the chance of email spoofing and phishing attempts, and ensures the integrity and security of email communications, providing greater trust in the sender&#8217;s identity.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_is_DKIM\"><\/span>What is DKIM?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>DomainKeys Identified Mail (DKIM) is an Office 365 email authentication technique. It adds a digital signature to the header of the email, that helps to verify an email message was not altered during transit and that it indeed came from the stated domain.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_is_DMARC\"><\/span>What is DMARC?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Domain-based Message Authentication, Reporting, and Conformance (DMARC) is an email authentication protocol designed to protect domain owners from email spoofing. It builds on SPF and DKIM by providing instructions on how to deal with emails that fail authentication attempts. DMRC tells receiving mail servers how to handle emails that fail SPF or DKIM checks.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Email_Authentication_Setup_SPF_policy_in_office_365\"><\/span>Email Authentication: Setup SPF policy in office 365<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><strong>Access your DNS Setting<\/strong><\/p>\n<p>To set up SPF, log into your domain registrar&#8217;s website and access the DNS management settings for your domain.<\/p>\n<p><strong>Create an SPF Record<\/strong><\/p>\n<p>Add a new TXT record in your DNS settings with the following value:<\/p>\n<p>v=spf1 include:spf.protection.outlook.com -all<\/p>\n<p>This record specifies that Office 365 Outlook\u2019s servers are authorized to send emails on behalf of your domain. If you use additional mail services, make sure to include them in the SPF record.<\/p>\n<p><strong>Verify the SPF Record<\/strong><\/p>\n<p>Use an online tool like MX Toolbox to ensure that your SPF record is configured correctly. This validation helps improve your email deliverability and prevents your emails from being marked as spam. For the better email security, DKIM and DMARC records must also be implemented in addition to SPF.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Office_365_Email_Authentication_Setting_up_DKIM\"><\/span>Office 365 Email Authentication: Setting up DKIM<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>For setting up DKIM sinning in Microsoft 365, your domain must be registered within the platform. Additionally, CNAME records must be added in your DNS configuration. This process is vital for securing your emails by ensuring they are protected against unauthorized alterations.<\/p>\n<p><strong>Enable DKIM Signing<\/strong><\/p>\n<ul>\n<li>First Open Microsoft Office 365 Defender portal and go to the &#8220;Email &amp;
