b1gMail is an open-source solution to run your own full-featured email service for personal use, your organization, or as a public provider.

🚀 Overview

b1gMail is a powerful, versatile open-source webmail and email management system that turns any web server into a complete email service provider. It handles thousands of users and millions of emails with efficient processing and caching, even on shared hosting without needing a dedicated server.

What problem does this project solve? It eliminates dependency on commercial email giants like Gmail or Outlook by providing a self-hosted alternative with full control, enhanced privacy, and customization. Who is it built for? Individuals seeking personal email independence, organizations for internal comms, and providers offering email to the public. Why did you build it? Originally launched as freeware by Patrick Schlangen, it became open-source under GPL to empower users with digital sovereignty and avoid proprietary lock-in.

✨ Key Features

Modern HTML5 user interface with Drag&Drop for emails, attachments, and files, plus integrated tools like address book, calendars, todo lists, notepads, cloud drives, SMS, and fax support
Smart folders that auto-populate based on criteria (e.g., unread, high-priority), powerful filtering for auto-actions like replies or notifications
Advanced spam protection via DNSBL blacklists and trainable Bayesian filter, virus scanning with ClamAV

Extensible plugin system for custom features without core modifications; optional b1gMailServer for POP3/IMAP/SMTP
