It works alongside other email authentication methods like SPF and DKIM to verify the authenticity of your emails. SPF (Sender Policy Framework) allows you to specify authorized IP addresses for sending emails on behalf of your domain. DKIM (DomainKeys Identified Mail) adds a digital signature to ensure the integrity and authenticity of your emails. By implementing DMARC, SPF, and DKIM, you significantly reduce the risk of your emails being classified as spam or phishing attempts and increase the likelihood of successful delivery.

Does Dmarc work?

DMARC email verification is an essential process to ensure email compliance and security. It protects your domain from email spoofing and unauthorized use, working alongside SPF and DKIM. SPF allows authorized IP addresses for email sending, while DKIM adds a digital signature for email integrity and authenticity. By implementing DMARC, SPF, and DKIM, you reduce the risk of spam or phishing classification and increase successful email delivery.

SPF
SPF (Sender Policy Framework)

It’s a diagnostic tool that presents a graphical view of SPF records. The grapical view allows people to quickly identify which servers are autorized to send on behalf of a domain email. SPF recor is a DNS txt record containing a list of the IP addreses that alloed to send email on behalf of the domain.
Find out if your SPF record has been published correctly.
Prevent mistakes in the formatting of your record, which can cause email deliverability issues
Discover any discrepancies regarding your SPF record.

Example of spf
v=spf1 ip6:1080::8:800:200C:417A/96 ~all
Allow any IPv6 address between 1080::8:800:0000:0000 and 1080::8:800:FFFF:FFFF.

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******@**********ng.com” data-original-string=”t7X/YcSNM3aqG4EgQ+h34Q==86euY3KcfCT+WOFrJwOw8zTLUxVEEBlsdLxterumcNhHOk=” 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 published correctly.

Reliable email checker

CONCLUSION:

Be prepared for your emails don’t be disrupted from the implementation of the news rules from Google and Yahoo. At the same time you are protected again the hijacked of your email domain sending malicious email, reputation suffer, people lose trus, and fraud is allowed to spread by the cibercriminals.

DMARC email authentication is crucial for ensuring the security and authenticity of your email domain. By implementing DMARC, you can verify the alignment of SPF and DKIM, providing an extra layer of protection against email spoofing and phishing attacks.

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.
