DMARC Alignment: Loose vs. Strict Alignment Modes

[mdabuhasan]

1. Advantages of Enabling DMARC
Once DMARC (Domain-based Message Authentication Reporting and Conformance) is enabled, a series of validation checks can be set to determine if an email is from the source it claims to be. DMARC offers great flexibility in terms of policies and alignment modes, which domain owners can configure to achieve the level of security they want.
2. Identifier Alignment Confirmation
Identifier alignment confirms that the domain names buy bulk sms service attached to each part of the email align correctly, indicating that the email is legitimate and cannot be part of a phishing or spoofing attempt. DMARC alignment is the process of aligning (or matching) the domains under each part of the email header during the validation check.
DMARC Alignment Process
If the message passes SPF and DKIM identifier alignment, DMARC will align the message. Ensure your emails are legitimate and protect against a range of email fraud attacks including phishing, spoofing, ransomware, and more. The DMARC validation protocol checks for DMARC identifier alignment to determine if an email domain could be spoofed.
Understanding DMARC Alignment
When you implement DMARC, you combine the results of SPF and DKIM to authenticate all emails coming from your domain. For any given email, DMARC uses what is called a "central identity," which is the domain found in the From header. This is considered the originating domain of the email, which includes your organization's domain name.
V. Conditions for DMARC Alignment
When an email from your domain arrives at the receiving server, its return path is checked and DKIM verifies the cryptographic signature. These two checks are done on two different domains. DMARC takes the verification results for each domain and checks if the domain used in SPF or DKIM matches the sender domain (central identity). If either is true, DMARC alignment is achieved.
DMARC Alignment Issues
There is a small problem, though. Anyone, including criminals, can buy a domain and implement SPF and DKIM. So, in theory, it is possible for anyone to send an email with your organization's domain in the From address (the central identity) and have their own domain's "return path" pass SPF validation.
7. Verify identifier alignment
Your verification identifier alignment marks whether your email sender is authorized to send email on behalf of your domain. This can be determined by checking the authenticity of the message against SPF (Sender Policy Framework) or DKIM (DomainKeys Identified Mail).
