About:
s-nail is a modern fork of the classic Heirloom mailx utility, providing a command-line interface for sending and receiving email. It features enhanced security, SMTP/IMAP protocol support, and scripting capabilities. The tool is designed for system administrators and developers who need a reliable, lightweight mail user agent for automation and direct mail handling.
Key Features:
  • Full SMTP and IMAP protocol support
  • Advanced scripting and automation capabilities
  • Enhanced security features and TLS support
  • POSIX-compliant and portable across Unix-like systems
Use Cases:
  • Sending automated system alerts and log reports via SMTP
  • Scripting email interactions and fetching mail from IMAP servers
  • Serving as a lightweight mail client in terminal environments
Alternatives:
  • mailx – The original Heirloom project is largely unmaintained; s-nail provides active development and modern features.
