The Domain Keys Identified Mail (DKIM) is a method of authenticating email messages. It adds an extra layer of protection to ensure the email is from the source it purports to come from, and can be verified without looking at the message content. Businesses use DKIM to prevent phishing attacks that use unauthorized email addresses. Domains with DKIM are validated as authentic, and emails sent from them will arrive in your inbox indistinguishable from legitimate messages sent directly from you.

DKIM (DomainKeys Identified Mail) is a sender authentication system that helps to protect your company against email phishing scams, spam, malware and other types of fraudulent emails. With email spoofing on the rise, DKIM can be a critical technology to deterring malicious messages from reaching your employees, partners and clients. Here's how it works: all mail servers have a public encryption key and a private decryption key.

When your domain signs up for DKIM, they provide the server with the public key that the server then adds to its digital DNS record. Email phishing scams are on the rise. DKIM helps organizations ...

What is the DKIM check?

DKIM (DomainKeys Identified Mail) or the DKIM check is an email verification technique that allows the receiver to check if an email was actually sent and authorized by the owner of that domain, thus giving assurance to its authenticity. DKIM stands for Domain Keys Identified Mail. It is one of the newest protocols created to combat email spoofing, phishing and server spoofing attacks.

This system ensures that your message has not been altered or faked during its transit from the sender’s mail server to recipient’s mail servers. From DKIM, to DMARC records, to SPF records, to domain keys and digital signatures, this guide will walk you step-by-step through setting up your email domains to be as safe and trustworthy as possible and DKIM signatures are not typically shown to end recipients, but your email service can show they are present in the header. If you look at the headers of an email from one of our addresses, you'll see a DKIM result there.

With a DomainKeys Identified Mail (DKIM) signature, you can be sure that the message of a specific email and the attachments haven’t been changed or modified. This way, you can identify the mails from your clients, colleagues or friends. The receiving system will examine the header, author information and the body text of an email to determine if it’s valid. If it is, it will check if there are any files attached to the email to decide whether they also have a valid DKIM signature.

Advantages of DKIM

DKIM allows the user to digitally sign and verify that their e-mail is authentic. This will substantially reduce the amount of phishing attacks, viruses, and spam. The DKIM system allows you to customize your signature in different ways for customization purposes.

There are many advantages of the DKIM system, some of them still undocumented. Here are just a few:

1.Be more reputable

Enable DKIM across all email domains in your organization. The more domains with DKIM signing on, the better your reputation becomes with other services because of the extra layers of accountability that DKIM offers. Using DKIM will unmistakably make you a more reputable email sender in the eyes of anyone who matters. Some examples would be: ISPs and Telcos (sending domains), Message systems (receiving domains), Partners, Customers, Business people, and any other third party service that you may encounter.

Add DKIM to your arsenal. Symantec's DKIM Sender Verify solution delivers accurate, real-time verification that will reassure customers, partners, and business contacts of the trustworthiness of your digital communications. Signing messages with DKIM offers you a layer of trust. Emails with DKIM signatures are resistant to spam filters, increasing the chances of them being opened. This makes our solution an ideal substitute for your existing software and perfects your reputation as a sender.

2.Avoid spam filters

The positive side of this is that sending mail to a company that uses DKIM will be less likely to fail, and if your email does not reach its intended recipient, it may still arrive at their spam folder. If you want to send messages that will not be filtered as spam, or if you would like the best possible chance of your emails reaching their destination, DomainKeys Identified Mail (DKIM) is a requirement.

By signing our emails with DKIM keys, and adding both Sender Policy Framework (SPF) and Domain Message Authentication Reporting and Conformance (DMARC), we’re attempting to take all the measures within our control to prevent spam filters from incorrectly diverting or quarantining your transactional email messages. DKIM or DomainKeys Identified Mail is an email authentication system that provides a cryptographic signature and allows the sender’s domain name to be used as a verifying domain name in the message header.

3.Bypass phishing

The ability to verify the authenticity of an email from it's source, you can ensure that you are not being duped by an opportunistic phishing attack. DKIM allows you to "bypass" a traditional spam filter if your recipients use something that is called a DKIM (DomainKeys Identified Mail) authentication system. Using DKIM you are assured that the origin of the email you received is from where it has been claimed. This is because a private key that corresponds to the domain used in the email header will have been created and only this key can be used to verify at the receiving end that it was not tampered with.

By checking this key, DKIM ensures authenticity of the sender from whom you received the email. This will ensure that your emails are not suspected as phishing emails, and are more likely to be trusted. Check out our email security page for more information on DKIM.
