DKIM

The DKIM selector is specified in the DKIM signature header and indicate where the public key portion of the DKIN keypair exist in DNS.

Find this DKIM signature contains an attribute “s=” which is the selector used. In the DKIM selector example below we can see the DKIM selector is s2048gl.

Example of DKIM record.

DKIM-Signature: v=1: a=rsa-sha256; c=relaxed/relaxed; d=marketing.com; s=s2048gl;

With the DKIM inspector you can check if the public part of your DKIM signature using the selector has been implemented corectly in the DNS of your domain.

The DMARC record ia a text entry into the DNS record that tell us your email domain’s policy after checking SPF and DKIM status. DMARC authenticates if either SPF,DKIM or both pass. This is referred to as DMARC alignment or identifier alignment.

Example of DMARC record

v=DMARC1; p=none; rua=mailto:wb******@ag.com” data-original-string=”pQlUO3tK4aFZxfKiVHo+L1PWRn8v1L/K4zKtCixUWhM=” title=”This contact has been encoded by Anti-Spam by CleanTalk. Click to decode. To finish the decoding make sure that JavaScript is enabled in your browser.

“v=” indicates this is a DMARC record
“P=” indicates the dmarc policy
“rua=” indicates where data should be sent

DMARC
The DMARC implementation starts with the publishing of a valid DMARC record. The DMARC is a record checker is a diagnostic tool that allows you to view the DMARC record of any given domain and test if the TXT record is valid and pu blished correctly.

The DMARC record, consisting of key elements such as v= for indicating the DMARC record, p= for specifying the DMARC policy, and rua= for determining where data should be sent, plays a vital role in this process. Make sure to publish a valid DMARC record and use a DMARC record checker to ensure its correctness. Safeguard your emails with DMARC as soos as you can.
