Lately, DMARC adoption has been reflecting an upward trend, underscoring the increasing awareness about email security, especially after Google and Yahoo’s announcements.

Troubleshoot DMARC problems for Google Workspace domains

 

Google Workspace encourages domain owners to use the three email authentication protocols, SPF, DKIM, and DMARC, to ensure outgoing emails are properly authenticated. This reduces the security gaps; otherwise, threat actors can exploit them to send phishing and spoofing emails from your domains. Moreover, from February 2024, Google has mandated DMARC deployment for regular and bulk email senders, urging domain owners or administrators to create a DMARC record in their DNS settings and specifying policies to handle emails that fail SPF and/or DKIM checks.

How do you receive DMARC reports on external email addresses?

How do you receive DMARC reports on external email addresses?

 

While most domain owners prefer receiving DMARC aggregate and forensic reports on internal email addresses, some want to have them in external inboxes. Internal email addresses refer to those belonging to the same domain for which the DMARC record is created. For example, if your organization’s domain is example.com, then an internal domain email address would be something like employee@example.com. On the other hand, external email addresses are the ones not belonging to that domain. For example, department@otherdomain.com.

DMARC helps prevent spoofed emails from bypassing spam filtering, but it’s just one part of a broader anti-spam strategy. Not all DMARC reports are equal; some show detailed recipient responses, while others only indicate success or failure. Understanding why a message failed is as important as knowing if it did.

How DMARC Manages Domains and Subdomains to Prevent Spoofing?

 

Businesses are now being mindful of protecting their domains with SPF, DKIM, and DMARC, but what about the times when you send emails from your subdomains? As a domain owner or administrator, you create a DMARC record that instructs how email-receiving servers should evaluate incoming emails from your domain to check their legitimacy. This process flows smoothly when domains are included, but it gets a bit complicated with the involvement of subdomains.

It all started when SPF came into play, followed by the amalgamation of Yahoo’s DomainKeys and Cisco’s Identified Internet Mail (IIM). This blog covers the journey of all three email authentication protocols in detail.
