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.
