DMARC

  • DNS

    Definition and structure of DMARC record.

     As an online business owner, a positive reputation and clients’ trust are significant values that take time and effort to build. Therefore, they must be protected. Because for cybercriminals, those are means to kill two birds with one shot! They approach your clients spoofing your business image to get illegal profits from them. 

    DMARC record definition.

    DMARC or Domain-based Message Authentication, Reporting, and Conformance record is a mechanism to let e-mail senders and recipients identify if an e-mail is truly coming from the sender it claims to be. DMARC also helps to define the actions to take when the e-mail gets authenticated and when it fails the authentication.

    What is an SPF record and How Does it Work?

    E-mailing is not new, but it keeps being a widely-used communication form. It’s the official way companies use to approach clients, employees, providers, etc. 

    Cybercriminals know it, so they try all sorts of malicious tricks to get into your communications. Spoofing here and there, they can send e-mails on companies or people’s behalf just to use their reputation and trustability to cheat others. 

    That’s why the SPF (sender policy framework) protocol emerged for making e-mailing a safer game.

    Before we start the topic of the TXT records, we are just going to scratch the surface of the DNS (Domain Name System). First, we will learn what DNS is, a DNS record, and the TXT record. That way, you can better understand the process of the verification of your domain.

    ​What is DNS?

    DNS is the universal translater that links domain names to their IP addresses. It is used on all websites and many services like, for example, web hosting and emails. You should know that DNS works with DNS records, which are instruction sets, linking various resources (names, IP addresses, services, etc.) together.
