Email Server Classification System
What We Test
We analyze DMARC, SPF, and DKIM configurations to determine how email servers handle incoming messages.
5 Dynamic Classes
Servers are classified into 5 categories that maintain an even 20% distribution. The classification boundaries shift dynamically based on test results.
Real-Time Updates
Results appear instantly as they're generated. The system automatically rebalances classes to maintain even distribution.
Magic File
A semi-intelligent classification file (magic-class-level-wobbling.txt) stores all test results for analysis and comparison.
