What is DKIM





Introduction

DKIM (DomainKeys Identified Mail) is an email authentication technology that adds a digital signature to outgoing emails. This allows receivers (Google, Yahoo, etc.) to identify and authenticate the sender. Digital signatures are unique to each domain and can be validated by the receiver.

This provides an extra layer of security for your emails so that you can be sure they're being read by someone who has access to your account or server—and not someone pretending to be you! This can prevent spam outbreaks or other malicious actions by hackers who want access into your accounts at companies like Amazon or Netflix.

Where DKIM authentication is required, an e-mail that passes DKIM will never be rejected due to failed authentication.

DKIM is not a requirement for email delivery, but it will help your email reach its destination. The DKIM signature ensures that an email was sent from you and not someone else (like an attacker). If you're sending email to Gmail, Yahoo or other major providers like this article's author, then you can use DKIM authentication in order to ensure that the recipient receives a legitimate message from you.

However if you're sending emails to smaller providers who don't support DKIM authentication yet but want their customers' data protected then we suggest using SPF instead of DKIM since SPF is more flexible than it's counterpart and allows more flexibility when determining whether or not something was sent by whom."

In order for DKIM to pass, the body of the message, subject lines and all headers must match what was defined when creating the DNS record. If any changes are made to the subject line or headers of the message after it has been signed, DKIM will fail.

DKIM is a DNS record. It's used to validate the sender of an email, and can be used to identify spam and phishing emails.

DKIM works by adding a signature to your messages that contains information about who sent them (from), when they were sent (from) and what domain they're from. This allows you to verify that any email coming from you has been sent by yourself or another authorized person on your behalf.

DKIM can be set up in your email service provider's application or via DNS records in your hosting account's cPanel.

DKIM can be set up in your email service provider's application or via DNS records in your hosting account's cPanel. You can set up DKIM with cPanel by adding a TXT record to your DNS.

You'll need to create a TXT record for each domain you want to receive DKIM-signed email for (including subdomains). To do this, log into your hosting account and navigate to the Domain Manager page. Click on "Domains" at the top of the menu bar and then select one of your subdomains from there. This will open up their settings page where you'll find a section called “DNS Records” where you can add new TXT records if they aren't already present there already (it may take some time while they update).

If you're using cPanel hosting with us, you can set up a TXT record to validate your domain with DKIM

If you're using cPanel hosting with us, you can set up a TXT record to validate your domain with DKIM.

To set up a DKIM record in cPanel:

  • Log in to the Control Panel and click on Domains.

  • Click on your domain name on the left side of the page. Then click Edit next to Digital Signatures (SES). This will open a new window where you can enter details about your signature or override settings for messages sent through this email address if necessary (e.g., SPF).
