DKIM is a registration standard for receiving and sending trusted domain-linked emails under the “Email Sender Policies”. There are methods such as SPF registration and DMARC registration Apart from this registration standard. DKIM record is an abbreviation of an English term, but it means "Domain Keys Identified Mail". The Turkish equivalent of this concept is "E-Mail Identified with Domain Name Keys", and the records are the ones used to reveal whether the source of the e-mails is reliable, whether it has been changed or whether there is a forgery.
What is DKIM Selector?
There is always a need to create a separate DNS record during DKIM records. In this respect, a text file is added to the domain for the unique DNS record that will be needed during the use of DKIM through the DKIM selective use. In this way, systems that change to have more than one key under the desired domain name, changing date ranges, and creation of changing signatures within the scope of third-party services are achieved. The DKIM selector is located in the header part of the DKIM signature and indicates that DNS is present in the public key part of the DKIM key pair.
Why is DKIM Registration Required?
The DKIM record systematically means that the source is reliable, unaltered, and free of forgery, as an e-mail moves between sending/receiving servers. Thanks to this registration, a private and public double key is generated during e-mail sending. The private one of these keys is used for e-mail signing to be published with the DNS TXT records of the public domain name. In this context, DKIM registration always has an important place. Because by using these records against identity theft or spam attacks, the email server can determine whether the message really came from the registered domain.
Frequently Asked Questions
The DKIM feature must be enabled via the e-mail provider in order to register, and then the TXT record, that is, the text must be added to the domain name DNS settings.
It is an important step to prevent the messages you send from the e-mail addresses you use with your domain name from falling into folders such as unnecessary, spam or blocked on the recipient's side. With DKIM registration, your domain name will be reliable in the eyes of e-mail providers and you will have the advantage of maintaining an e-mail reputation.
Thanks to the SPF record, which is used as another standard, the server IP addresses that are sent on your behalf are determined. However, thanks to the DKIM registration, barcoding is provided in the e-mails sent.
When an e-mail is sent via the encryption system on the server, barcoding is done with DKIM, while the rule standards that enable reporting of violations in SPF and DKIM protocols are called DMARC.
Thanks to the signature in the DKIM record, the sender's accuracy is guaranteed because barcoding is done when an e-mail comes out from the sender's server. Therefore, the signature provides a very important security procedure.
