Overview of Features
Domain Protection receives DMARC reports sent from ISPs and other email recipients and visualizes their contents.
Many systems within a company send emails, and if they do not support email authentication (SPF or DKIM) or are improperly configured, authentication errors may occur.
By using Domain Protection, you can easily identify mail servers with authentication errors and take effective countermeasures against spoofed emails by appropriately configuring and operating DMARC policies.
DMARC Record Generation and Management
Domain Protection issues DMARC Records for registered organizational domains and generates email addresses to specify in the rua field.
