## About Email Sorter Ultimate
Email Sorter Ultimate is an enterprise-grade Windows desktop application designed to categorize high-volume email lists based on true mail exchange (MX) server infrastructure. Rather than relying on basic domain extension matching, Email Sorter Ultimate queries DNS Type 15 records in real time to identify the exact mail servers behind every address—automatically isolating Microsoft 365, Google Workspace, Yahoo, AOL, Yandex, GoDaddy, and enterprise webmail hosts. Featuring a proprietary Zimbra Judger engine, the software identifies Synacor Zimbra Collaboration Suite (ZCS) hosts by evaluating secondary MX trees, webmail REST/SOAP API signatures, and STARTTLS SSL certificates across ports 25 and 587. Email Sorter Ultimate runs 100% locally on the user's machine, executing up to 50,000 DNS lookups per minute with zero SMTP handshake pinging, ensuring zero spam-trap or bounce risks during list preparation. Key Features & Capabilities DNS MX Record Resolution: Automatically classifies bulk lists across 60+ pre-configured mail providers by resolving host server MX records. Proprietary Zimbra Judger: Accurately isolates hidden Zimbra hosted domains using deep signature checks, secondary MX trees, and SSL/TLS certificate evaluation. High-Speed Async Engine: Processes over 500,000 records in a single batch at speeds exceeding 50,000 addresses per minute. Zero Bounce / Spam-Trap Risk: Performs parsing strictly through local DNS queries without initiating active SMTP connections to recipient MTAs. Automated List Hygiene: Removes duplicate entries, syntax errors, and corrupted email formats automatically during file import. Flexible File I/O: Supports importing .txt, .csv, and .xls files, exporting categorized output files organized by server host. On-Device Data Privacy: Operates entirely locally without uploading contact data to external cloud servers, maintaining full GDPR and CCPA compliance.
