It then compares the IP address of the server that sent the email to the list of authorized IPs in that record. If there is no match, the server issues a 550 error.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At <strong>mybox<\/strong>, we provide a standard SPF record that covers all our mail infrastructure. If your domain is registered or parked with us, this record is usually generated automatically.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Distinction_Block\"><\/span>Distinction Block<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>MX vs. SPF<\/strong> <strong>MX (Mail Exchange)<\/strong> records tell the world where to <em>deliver<\/em> mail sent to you. <strong>SPF (Sender Policy Framework)<\/strong> records tell the world which servers are allowed to <em>send<\/em> mail from you. Both must be correct for your email to function reliably.<\/p>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_Resolve\"><\/span>How to Resolve<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">To fix a 550 SPF error, you must verify that your DNS zone contains the correct entries.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>1. Access DNS Management<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Log in to your <strong>mybox<\/strong> panel and navigate to the <strong>Domains<\/strong> section.<\/li>\n\n\n\n<li>Select your domain from the list.<\/li>\n\n\n\n<li>Go to the <strong>Parked<\/strong> tab and click the <strong>Manage DNS<\/strong> button.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2. Verify the SPF Record<\/strong> Look for a <strong>TXT<\/strong> record. To ensure your mail is delivered correctly through <strong>mybox<\/strong>, it must look exactly like this:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>&#8220;v=spf1 include:_mail.mybox.com ~all&#8221;<\/strong><\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>3. Verify MX Records<\/strong> While in the DNS manager, ensure your MX records are pointing to the correct <strong>mybox<\/strong> delivery nodes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><code>mx-1.mybox.com<\/code><\/li>\n\n\n\n<li><code>mx-2.mybox.com<\/code><\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Practical_Implications\"><\/span>Practical Implications<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Propagation Time:<\/strong> If you recently updated these records, it can take anywhere from <strong>1 to 24 hours<\/strong> for the changes to spread across the internet. During this time, you may still see the 550 error.<\/li>\n\n\n\n<li><strong>External DNS:<\/strong> If your domain is registered elsewhere (e.g., Godaddy or Namecheap) but points to <strong>mybox<\/strong> hosting, you must manually add the SPF string above to the DNS settings at your registrar.<\/li>\n\n\n\n<li><strong>Multiple Services:<\/strong> If you use an additional service to send mail (like a newsletter tool or CRM), you must &#8220;include&#8221; them in the same SPF record. You should never have two separate SPF records for one domain.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Summary\"><\/span>Summary<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A 550 SPF error is a signal that your domain&#8217;s &#8220;identity card&#8221; is missing or wrong.
