Making email-domain configuration understandable.
MXFend · Engineering overview
The problem
Email authentication involves several records and protocols. A domain owner needs to understand what a check found and what to investigate next, rather than receive an unexplained pass or fail.
Conceptual flow, simplified for this overview.
Engineering focus
- Email authentication and domain diagnostics
- SPF, DKIM and DMARC checks
- Explanations that connect technical findings to configuration
Making diagnostics useful
Authentication records are only useful to a domain owner when the findings are understandable. The product brings checks and explanations together, rather than presenting protocol details without context.
The scope of this overview is the public diagnostic tools. It is deliberately separate from any future monitoring or commercial features.
Current status
The public email-authentication and domain diagnostic tools are available at MXFend.
