Email is one of the most important communication tools for individuals and businesses. Every day, billions of messages are exchanged, carrying everything from personal conversations to business contracts and financial details. But this importance also comes with risks. Hackers, spammers and fraudsters are constantly exploiting email systems to try to spam, steal data and spoof trusted domains. SPF, DKIM and DMARC will be active here. These three security features protect against mail and domain misuse. If set correctly, it will work together to prevent mail domains from being exploited for spam and phishing and ensure that real emails are delivered to the inbox. In this article, I will explain the role, mechanism, and important reasons for each function.

Every day, millions of fake emails are sent over the Internet. Some of these emails pretend to come from well-known brands, government offices, or even from your own company. This is called mail spoofing and is one of the biggest problems in digital communication. Whenever criminals misuse their territories and send spam or phishing mail, their reputation as a business is at a risk. It makes the customer distrust their emails and emails like Gmail and Outlook can even block emails altogether. Unless you take the right protection measures, the following risks will affect your business:
is the first step in domain protection. The SPF works like an approved sender list. Tell the mail server which mail system is allowed to send mail in your domain. For example, your email is mycompany.com, SPF would make sure only known servers are issued to send messages on their behalf. In case an attacker tries to deliver mail over the name of mycompany.com with a different server, the receiving server will examine the SPF record and refuse the delivery of the mail.

DKIM (DomainKeys Identified Mail) adds a protection layer. DKIM provides you with an individual digital signature to every email you make. It will be appended to the message header to demonstrate that the mail is not compromised along the way between the server and the recipient. The signature is authenticated when the message is transmitted to the receiving mail server based on the DKIM record of the domain. In case the signature is same, the email will be considered to be real.

DMARC (Domain-based Message Authentication, Reporting, and Conformance) ties SPF and DKIM together. The DMARC can define the operation of the mail server in case the message does not pass through the SPF or the DKIM test. The following options are available:
DMARC also provides reports on those who attempt to exploit your domain and send emails. These reports help to understand and stop attacks before damage occurs.

Each function is worth it alone, but it forms a complete protection system by working together.
This three-step process only enables trusted and authentic emails from your domain to reach your inbox, blocking counterfeit and malicious emails.
