checks may include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>sender authentication verification<\/li>\n\n\n\n<li>domain reputation analysis<\/li>\n\n\n\n<li>spam and phishing detection<\/li>\n\n\n\n<li>message formatting validation<\/li>\n\n\n\n<li>server reputation checks<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">If one or more checks fail, Gmail may reject the

class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">SPF (Sender Policy Framework) is a DNS record that defines which servers are allowed to send email for a domain.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If an SPF record is missing or configured incorrectly, Gmail may treat messages as suspicious.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Missing_or_invalid_DKIM_signature\"><\/span>Missing or invalid DKIM signature<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">DKIM (DomainKeys Identified Mail) adds a cryptographic signature to outgoing messages.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This allows receiving servers to verify that the message was not modified during transmission.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Invalid or missing DKIM signatures can negatively affect email trust.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Missing_DMARC_policy\"><\/span>Missing DMARC policy<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">DMARC works together with SPF and DKIM to define how receiving servers should handle messages that fail authentication checks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Without DMARC, domain protection and sender validation are weaker.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Poor_sender_reputation\"><\/span>Poor sender reputation<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Gmail evaluates the reputation of:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>sending IP addresses<\/li>\n\n\n\n<li>sending domains<\/li>\n\n\n\n<li>historical email behavior<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Large volumes of unwanted messages, spam complaints, or previous abuse can reduce reputation and affect delivery.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Suspicious_message_content\"><\/span>Suspicious message content<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Messages may be rejected if they contain:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>misleading links<\/li>\n\n\n\n<li>phishing indicators<\/li>\n\n\n\n<li>malicious attachments<\/li>\n\n\n\n<li>spam-like content patterns<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Content filtering works alongside technical verification mechanisms.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Incorrect_DNS_configuration\"><\/span>Incorrect DNS configuration<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">DNS issues can affect email delivery, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>missing reverse DNS (PTR) records<\/li>\n\n\n\n<li>incorrect MX records<\/li>\n\n\n\n<li>inconsistent domain configuration<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These problems can reduce trust in the

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Google periodically updates its email security requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For domains sending larger volumes of email, Gmail may require:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>SPF authentication<\/li>\n\n\n\n<li>DKIM authentication<\/li>\n\n\n\n<li>DMARC configuration<\/li>\n\n\n\n<li>encrypted SMTP connections<\/li>\n\n\n\n<li>low spam complaint rates<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Failure to meet these requirements can result in delivery problems or message rejection.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_is_normal_behavior\"><\/span>What is normal behavior?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Not every rejected message indicates a server failure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Email providers regularly update filtering systems to reduce spam, phishing, and abuse. Because of this, a message may be accepted by one provider while being rejected by another.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Delivery policies can also change over time as security standards evolve.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"When_to_investigate_further\"><\/span>When to investigate further<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Additional verification is recommended if:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>multiple Gmail recipients stop receiving messages<\/li>\n\n\n\n<li>bounce messages mention SPF, DKIM, or DMARC failures<\/li>\n\n\n\n<li>delivery problems affect only specific providers<\/li>\n\n\n\n<li>rejection rates increase suddenly<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">In these situations, reviewing authentication records and mail server configuration can help identify the cause.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Summary\"><\/span>Summary<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Gmail may reject email messages when authentication checks fail, sender reputation is poor, DNS configuration is incorrect, or message content triggers security filters. Proper SPF, DKIM, and DMARC configuration helps improve delivery reliability and trust between mail systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div>","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":0,"template":"","format":"standard","manualknowledgebasecat":[24],"manual_kb_tag":[1266,3532,4912,6068,6069,6070,339,797,996,1002],"class_list":["post-9059","manual_kb","type-manual_kb","status-publish","format-standard","hentry","manualknowledgebasecat-gmail","manual_kb_tag-email-rejection","manual_kb_tag-sender-authentication","manual_kb_tag-sender-reputation","manual_kb_tag-gmail-rejection","manual_kb_tag-dkim-signature","manual_kb_tag-domain-reputation","manual_kb_tag-email-deliverability","manual_kb_tag-email-authentication","manual_kb_tag-dmarc-policy","manual_kb_tag-spf-record"],"_links":{"self":[{"href":"https:\/\/mybox.com\/help\/ro\/wp-json\/wp\/v2\/manual_kb\/9059","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/mybox.com\/help\/ro\/wp-json\/wp\/v2\/manual_kb"}],"about":[{"href":"https:\/\/mybox.com\/help\/ro\/wp-json\/wp\/v2\/types\/manual_kb"}],"author":[{"embeddable":true,"href":"https:\/\/mybox.com\/help\/ro\/wp-json\/wp\/v2\/users\/1"}],"version-history":[{"count":2,"href":"https:\/\/mybox.com\/help\/ro\/wp-json\/wp\/v2\/manual_kb\/9059\/revisions"}],"predecessor-version":[{"id":9061,"href":"https:\/\/mybox.com\/help\/ro\/wp-json\/wp\/v2\/manual_kb\/9059\/revisions\/9061"}],"wp:attachment":[{"href":"https:\/\/mybox.com\/help\/ro\/wp-json\/wp\/v2\/media?parent=9059"}],"wp:term":[{"taxonomy":"manualknowledgebasecat","embeddable":true,"href":"https:\/\/mybox.com\/help\/ro\/wp-json\/wp\/v2\/manualknowledgebasecat?post=9059"},{"taxonomy":"manual_kb_tag","embeddable":true,"href":"https:\/\/mybox.com\/help\/ro\/wp-json\/wp\/v2\/manual_kb_tag?post=9059"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
