rss2email

rss2email is a command-line utility that monitors RSS and Atom feeds and delivers new entries to email addresses. It runs as a local process (or scheduled job), tracks seen items, and sends email via a local sendmail-compatible MTA or an SMTP/LMTP server.

Key Features

• CLI-first tool with the r2e command for adding feeds, initializing config/data, and running feed checks
• Supports sending via local sendmail/compatible MTA, SMTP, or LMTP with authentication and TLS options
• Stores configuration and seen-item database in XDG-style locations (config and data files by default)
• Post-processing hook support to modify or sanitize entries before sending (custom modules/functions)
• Options for HTML mail, date header control, GUID/trust settings, and per-run no-send to seed state
• Lightweight dependencies (Python-based, uses feedparser and html2text) and packaged for multiple Linux distributions

Use Cases

• Receive email notifications for new posts from selected RSS/Atom feeds without visiting a feed reader
• Integrate feed-to-email delivery into existing mail workflows or mailboxes on a server
• Schedule periodic feed checks via system cron or task scheduler to distribute updates to users

Limitations and Considerations

• No built-in web UI or multi-user management; primarily single-user CLI usage
• Relies on external mail delivery configuration; deliverability and authentication depend on local MTA or SMTP settings
• Uses a local JSON feed database; not designed for very large-scale feed fleets or multi-tenant hosting without custom adaptations

rss2email is a simple, pragmatic tool for users who prefer receiving feed updates by email and who can manage mail delivery and scheduling on their host. It emphasizes configurability and extensibility via post-process hooks while remaining command-line focused.
