Penguin Mail: Open-Source Rust Email Client for Linux With Optional AI Assistant

Penguin Mail 1.0.5 is a free, GPL-3.0-or-later open-source email and calendar app for x86_64 Linux that supports Gmail, Microsoft, and any IMAP or POP3 account. Its optional assistant stays off until a user chooses a model, can run locally through LM Studio or Ollama, and asks before sending mail or changing settings.
