All you need to know about DKIM"},"content":{"rendered":"\n<p>Domain Keys Identified Mail (DKIM) is a technological norm that helps deter spam, spoofing, and phishing from email senders and recipients. This is a type of email authentication that allows an individual to assert accountability for a message in a manner that the receiver may validate.<\/p>\n\n\n\n\n\n<p>DKIM uses a &#8220;public-key cryptography&#8221; approach to verify that an email message has been sent from an authorized mail server to detect forgery and prevent harmful email delivery such as spam.<\/p>\n\n\n\n<p><strong>DKIM Signature- <\/strong>A DKIM signature is an email address header. The header includes values that enable a receiving mail server to confirm the email message by looking for the DKIM key of a sender and using it to check the signature encrypted.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How it works ? <\/strong><\/h2>\n\n\n\n<p>DKIM operates by applying a digital signature to an email message header. You can then check this signature against a shared cryptographic key stored in the DNS database of the company.<\/p>\n\n\n\n<ul>\n<li>A cryptographic key is released by the domain holders.&nbsp;<\/li>\n\n\n\n<li>This is formatted specifically as a TXT record in the overall DNS record of the domain.<\/li>\n\n\n\n<li>The application produces and applies the special DKIM signature to the document header after a letter is sent by an outbound mail server.<\/li>\n\n\n\n<li>Inbound mail servers then use the DKIM key to detect and decrypt the signature of the message and compare it to a fresh version.&nbsp;<\/li>\n\n\n\n<li>The message can be proven authentic and unchanged in transit if the values match, and therefore not forged or altered.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How is it related to SPF ?<\/strong><\/h2>\n\n\n\n<p>DKIM and SPF are all protocols that require various aspects of email authentication. Complementary issues are addressed.<\/p>\n\n\n\n<ul>\n<li>SPF requires senders to specify which IP addresses for a particular domain are allowed to send mail.<\/li>\n\n\n\n<li>DKIM offers a digital signature and security key to ensure that an email message has not been faked or updated.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Advantages<\/strong><\/h2>\n\n\n\n<ul>\n<li>Bypass spam filters.<\/li>\n\n\n\n<li>Avoid getting phished.<\/li>\n\n\n\n<li>Improve Reputation.<\/li>\n<\/ul>\n\n\n\n<p>Click here to read more about <a href=\"https:\/\/www.tikaj.com\/blog\/what-is-spf-why-use-spf-what-are-its-limitations\/\" data-type=\"link\" data-id=\"https:\/\/www.tikaj.com\/blog\/what-is-spf-why-use-spf-what-are-its-limitations\/\">SPF<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Domain Keys Identified Mail (DKIM) is a technological norm that helps deter spam, spoofing, and phishing from email senders and recipients.
