hMailServer 6.2.0 introduces the hMailServer Control Panel - a brand-new, modern desktop administration app - alongside the full 6.x server. The .NET 8 Desktop Runtime is now bundled and installed automatically when missing - no separate downloads.
hMailServer Control Panel (new)

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

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

The classic Administrator remains included.
