Frequently Asked Questions

The term DKIM is derived from the initials of "Domain Keys Identified Mail." DKIM records ensure that electronic emails come from a reliable source, have not been altered, and are not subject to fraud.

You can create your DKIM record by enabling the DKIM feature on your email service server and adding the resulting text (TXT record) to your domain's DNS settings.

You can create a DKIM record to prevent your sent emails from landing in Spam/Junk/Unwanted folders, help mark your domain as trustworthy with email providers, thwart fraud attempts, and maintain your email reputation.

You can query the DKIM record (TXT record) for the relevant domain using the 'dig' command via console or shell access.

SPF determines which server IP addresses can send mail on your behalf. DKIM, on the other hand, is a system that encodes these transmissions.

DKIM is defined as the barcode for every email sent using encryption by the server, while DMARC refers to rule sets that report situations where DKIM procedures are violated, often in conjunction with SPF.

Updating a DKIM record is easy and can be done through the domain's DNS management screen (TXT record).

To permanently disable an existing DKIM record, simply delete the relevant TXT record from the domain's DNS management screen.

An example of a DKIM record is displayed in the following format:

dk1024-2012._domainkey.mxlayer.com. 600 IN TXT "v=DKIM1; o=-; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC1TaNgLlSyQMNWVLNLvyY/neDgaL2oqQE8T5illKqCgDtFHc8eHVAU+nlcaGmrKmDMw9dbgiGk1ocgZ56NR4ycfUHwQhvQPMUZw0cveel/8EAGoi/UyPmqfcPibytH81NFtTMAxUeM4Op8A6iHkvAMj5qLf4YRNsTkKAV;"

DKIM signature is crucial as it guarantees the sender's authenticity by barcoding each outgoing electronic message.

A unique private key generated for the sending domain determines the DKIM signature. To view the DKIM signature for your domain, run the following commands sequentially in the command prompt: 'set type=txt' and '12317._domainkey.yourcompany.com.'

You can easily add the DKIM signature to your domain's DNS management screen (TXT record) by following the instructions related to the selector parameters.
