The Control Panel

A .NET 8 WPF application with Fluent/Windows 11 design (Mica window), light and dark themes, animated live charts, and the familiar navigation tree from the classic Administrator: Welcome, Status, Domains, Rules, Settings > Advanced, Utilities.

• Animated dashboard with KPI cards plus live delivery-throughput and session charts.
• Domains and accounts, with an account editor for quota, password, forwarding and vacation, plus aliases and distribution lists with member management.
• Delivery queue with Deliver now and Remove, plus live log streaming.
• Rules with a graphical IF/THEN editor covering criteria and actions.
• Settings: Protocols, Delivery, Routes, Anti-spam (SPF/DKIM/DMARC/greylisting/SpamAssassin), Anti-virus, Logging.
• Advanced: Auto-ban and SSL/TLS, Performance and scripting, SSL certificates, TCP/IP ports, IP ranges with a permission editor, Incoming relays, and DANE/DNSSEC, MTA-STS, ARC, TLS-RPT, ACME, REST API, web services and metrics.
• Utilities: Backup and restore, MX query, Server sendout, Diagnostics.
• Ctrl+K command palette, guaranteed text contrast, consistent spacing.

The classic Administrator remains included. So does the Web Control Deck, the browser admin served at the REST listener root.
