SPF: A Foundation for Email Authentication

on November 7, 2024

Sender Policy Framework (SPF) is a fundamental email authentication protocol that helps verify the authenticity of the sender’s IP address. By defining which IP addresses are authorized to send emails on behalf of a domain, SPF helps prevent email spoofing and phishing attacks.

How SPF Works

An SPF record is a DNS record that specifies the IP addresses or domains that are authorized to send emails for a particular domain. When a receiving mail server receives an email, it checks the SPF record of the sender’s domain to verify if the sending IP address is listed. If the IP address matches one of the authorized addresses, the email is likely legitimate.

DMARC: The Shield for Your Email Domain

By Jane Doe on November 2, 2024

DMARC (Domain-based Message Authentication, Reporting, and Conformance) is a powerful email authentication protocol that helps protect your domain from spoofing and phishing attacks. By implementing DMARC, you can significantly improve the security and deliverability of your emails.  

How DMARC Works

DMARC leverages two other email authentication protocols, SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail), to verify the authenticity of emails. Here’s a breakdown of the process:  

SPF Verification: The receiving mail server checks the SPF record to determine if the sending server is authorized to send emails on behalf of the domain. DKIM Verification: The receiving server verifies the DKIM signature to confirm that the email hasn’t been tampered with during transit. DMARC Enforcement: If both SPF and DKIM checks pass, the email is likely legitimate. However, DMARC allows you to specify how the receiving server should handle emails that fail authentication. You can choose to: None: No specific action is taken. Quarantine: The email is quarantined for review. Reject: The email is rejected and not delivered. Benefits of Implementing DMARC

Why Correct Email Authentication Matters

By Tomasz Pado on November 1, 2024

In today’s digital age, email has become an indispensable tool for both personal and professional communication. However, with the increasing prevalence of cyber threats, ensuring the security and deliverability of your emails is paramount. This is where email authentication protocols like SPF, DKIM, and DMARC come into play.

What are SPF, DKIM, and DMARC?

SPF (Sender Policy Framework): This protocol specifies which IP addresses are authorized to send emails on behalf of a domain. By verifying the sender’s IP address, SPF helps prevent email spoofing. DKIM (DomainKeys Identified Mail): DKIM adds a digital signature to outgoing emails, allowing recipients to verify the authenticity of the message and its sender. DMARC (Domain-based Message Authentication, Reporting, and Conformance): DMARC is a policy layer that leverages SPF and DKIM to protect your domain from unauthorized use and improve email deliverability. It also provides insights into email traffic and potential threats. Why is Correct Configuration Crucial?

DKIM: A Digital Signature for Your Emails

on August 3, 2024

DomainKeys Identified Mail (DKIM) is an email authentication protocol that adds a digital signature to outgoing emails. This signature allows receiving mail servers to verify the authenticity of the email and its sender.

How DKIM Works

Digital Signature: A private key is used to sign the email header. Public Key Publication: The corresponding public key is published in a DNS record. Signature Verification: The receiving mail server uses the public key to verify the digital signature. Key Benefits of DKIM
