DMARC DNS Record Subdomains - Apr 2023

Known Issue

Date Logged	April 3rd, 2023
Product(s)	DMARC Analyzer
Status	Not Fixing

Issue

Only DMARC DNS records for main domains are displayed on the Domains page. A DMARC DNS record for a subdomain is ignored when not treating the subdomain as a main domain. 

This is a known limitation not on the Mimecast Product Team Roadmap to resolve. 

Workaround

• All subdomains that have DMARC DNS records should be treated as main domains.
• Follow the steps below to set this up:
  • In the subdomain menu, select the option Treat as main domain.
  • The subdomain will then be listed on the top level of the domains page, with its own DMARC DNS record.
