DMARC: What is it and how does it work?
DMARC is an acronym for Domain-based Message Authentication, Reporting & Conformance. It is an email authentication protocol. This email authentication protocol has been designed with the aim of protecting domains against phishing and spoofing practices . DMARC works in conjunction with two other authentication protocols: SPF (Sender Policy Framework) and DKIM (domainKeys Identified Mail), both protocols being mandatory to configure.
SPF allows you to define which servers are authorized to send emails on your behalf. DKIM , on the other hand, is responsible for adding digital signatures to emails to verify that they have not been altered during transit. And finally, DMARC uses the results of these two protocols to determine the validity of an email . It also adds how to handle if authentication fails.
Combining all three protocols significantly reduces the risk of phishing , improving overall email security.

How to configure DMARC
Implementing DMARC as a security measure for your emails may seem complicated, but following these steps will make it easier:
1. Set up SPF and DKIM . In order to properly run DMARC, you must have both SPF and DKIM records enabled. For the former, go to your hosting or domain provider's DNS management panel. Add a TXT record in your domain host's DNS that you're going to use as a custom sender for sending your email marketing campaigns.
For the second one, generate a DKIM key using a DKIM key generation tool provided by your email service provider. Now add a TXT record in your DNS for the DKIM public key. Next, add the DKIM record to your DNS, this is done by adding a TXT record in your DNS.
In MDirector, the use of this public key cryptography in DKIM is already configured. Therefore, you only have to insert the TXT with the md2 selector and the public key in the DNS host of the domain to use as your custom sender.

2. Create a DMARC record. Once you have SPF and DKIM set up, you can proceed to implement DMARC. You will first need to log in to your DNS provider and go to the admin panel. Next, create a new TXT record in your DNS that will specify how to handle emails that fail SPF and DKIM authentications.
3. Monitor DMARC reports. Once you've set it up, you'll be able to receive reports on the authentication of emails sent from your domain. This will help you identify and fix potential issues before you have to implement stricter policies. Specify an email address where you'll receive DMARC reports on email authentication.
4. Set DMARC policy (none, quarantine, reject). Once you are sure that all your legitimate emails pass SPF and DKIM validations, you can change the DMARC policy to be stricter with unauthenticated emails. “ none ” means taking no action but collecting reports; “ quarantine ” means sending emails to the spam folder; and finally, “ reject ” blocks those that have not been authenticated.
starting by setting a “none” policy and if everything goes well, you can raise it to “quarantine”, and then raising it to “reject” days later.
5. Save and apply changes . Collect the changes that have been made to the DNS configuration and apply them.
6. Review and update regularly . Periodically review your DMARC settings to ensure they remain effective against new threats.
Using DMARC with MDirector
As an email marketing platform , MDirector includes DKIM, SPF, and DMARC security settings to ensure that emails are authenticated. This way, the domain you use for your custom sender will be protected against phishing and spoofing attacks . Users must first configure SPF and DKIM before enabling the DMARC protocol .
This implementation will simplify the process and ensure that emails sent from MDirector meet authentication and security standards . In addition, our team will monitor and offer you support if you require it for the authentication of these absolutely essential, necessary and mandatory protocols.
Ultimately, DMARC is a crucial tool for email protection. It provides a robust defense against spoofing and phishing. Correctly implementing DMARC, SPF, and DKIM protocols may seem like a daunting task, but the reality is that the b germany whatsapp number data enefits outweigh the effort, and it is mandatory, as you cannot send emails without having these three protocols configured. By authenticating emails and reducing the risk of fraud , you can maintain the integrity and security of email communications.
With our platform you will have the guarantee of proper configuration and continuous monitoring. The importance of the DMARC protocol lies in protecting your email, your business and your reputation .
