Turbo MTA

Enterprise-grade SMTP delivery for Windows, without the enterprise invoice.

Turbo MTA is a high-performance Mail Transfer Agent for Windows Server, built on .NET 8 with a visual WinForms control panel instead of cryptic config files. It delivers the core capabilities serious senders rely on - a multi-port SMTP server with AUTH and STARTTLS, DKIM signing, VirtualMTA IP pools with automatic rotation, per-domain rate limiting, and a Redis + RocksDB queue engine - all manageable from a live dashboard with charts, queue search, and a built-in DKIM/SPF configurator. It installs as a native Windows Service with PowerShell/MSI deployment, firewall automation, and auto-restart…
