DKIM is a validation system that detects email spoofing. It allows your mail server to check whether a domain&#8217;s administrators authorized email from a domain. The email includes a digital signature that your mail server uses to verify the sender&#8217;s public key in their DNS record.<\/p>\n<p>SPF uses DNS records to prevent email spoofing. If an email message uses falsified sender addresses, SPF uses the DNS record for the sender&#8217;s domain to detect the modification in the email&#8217;s header.<\/p>\n<h3 id=\"HowtoKeepyourEmailOutoftheSpamFolder-DMARC\"><span class=\"ez-toc-section\" id=\"DMARC\"><\/span>DMARC<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>DMARC (Domain-based Message Authentication, Reporting &amp; Conformance) is a technical specification to help reduce the potential for email-based abuse. A DMARC policy uses DNS to confirm that an email message uses a valid DKIM and SPF record, and that the <code>From:<\/code> header matches those records.<\/p>\n<p>Many large email networks require that you use a DMARC policy to help protect their users from spam email. To prevent email rejections or spam flags within these networks, your server <strong>must<\/strong> use a DMARC policy.<\/p>\n<h2 id=\"HowtoKeepyourEmailOutoftheSpamFolder-Configureyourserver'sPTRrecord\"><span class=\"ez-toc-section\" id=\"Configure_your_servers_PTR_record\"><\/span>Configure your server&#8217;s PTR record<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>A PTR record resolves an IP address to a domain name. A PTR record resembles a reversed A record. Configure the PTR record of the primary IP address of your server to use the hostname of your server. If you have configured Exim to use a different IP address, ensure that the PTR record of that IP address uses the hostname of your server.<\/p>\n<p>A record resemble the following example:<\/p>\n<div class=\"code panel pdl conf-macro output-block\" data-hasbody=\"true\" data-macro-name=\"code\">\n<div class=\"codeContent panelContent pdl\">\n<pre class=\"syntaxhighlighter-pre\" data-syntaxhighlighter-params=\"brush: bash; gutter: true; theme: Default\" data-theme=\"Default\">server:~ root$ dig mail.tnadu.com +short\r\n192.168.1.15\r\nserver:~ root$<\/pre>\n<\/div>\n<\/div>\n<p>PTR records resemble the following example:<\/p>\n<div class=\"code panel pdl conf-macro output-block\" data-hasbody=\"true\" data-macro-name=\"code\">\n<div class=\"codeContent panelContent pdl\">\n<pre class=\"syntaxhighlighter-pre\" data-syntaxhighlighter-params=\"brush: bash; gutter: true; theme: Default\" data-theme=\"Default\">server:~ root$ dig -x 192.168.1.15 +short\r\nmail.tnadu.com.\r\nserver:~ root$<\/pre>\n<\/div>\n<\/div>\n<h2 id=\"HowtoKeepyourEmailOutoftheSpamFolder-Spamandothernetworks\"><span class=\"ez-toc-section\" id=\"Spam_and_other_networks\"><\/span>Spam and other networks<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>If email networks such as\u00a0<a class=\"external-link\" href=\"https:\/\/support.google.com\/mail\/troubleshooter\/2920052\" rel=\"nofollow noopener\" target=\"_blank\">Gmail<\/a>\u2122, <a class=\"external-link\" href=\"https:\/\/help.yahoo.com\/kb\/postmaster\/yahoo-mail-deliverability-faqs-sln24439.html\" rel=\"nofollow noopener\" target=\"_blank\">Yahoo<\/a>, or\u00a0<a class=\"external-link\" href=\"https:\/\/support.live.com\/eform.aspx?productKey=edfsmsbl3&amp;ct=eformts&amp;scrx=1\" rel=\"nofollow noopener\" target=\"_blank\">Outlook<\/a>\u00a0mark your server&#8217;s email as spam, you <strong>must<\/strong> identify the reason and resolve the problem.
