b1gMail

b1gMail is a web-based email and collaboration suite designed to let organizations run their own hosted email services. It provides webmail, groupware features and an administration control panel for managing users, domains and server integrations.

Key Features

• Full-featured webmail interface with HTML5 features (drag & drop for emails and attachments) and modern UI components.
• Groupware: address book, calendar, tasks/todo lists, notes and a cloud drive integrated into the web UI.
• Administration Control Panel (ACP) for multi-tenant administration, user/group management and setup wizards.
• Extensible plugin system allowing installation of additional features via plugins without modifying core code.
• Spam and virus protection including DNS blacklist filtering, a trainable Bayesian spam filter and ClamAV integration for virus scanning.

Use Cases

• Hosting providers or organizations that want to offer branded hosted email and groupware to customers or internal users.
• Small-to-medium organizations needing an integrated webmail, calendar and file drive solution with centralized admin controls.
• Service operators who want an extendable webmail portal with plugin support and configurable filtering/antivirus pipelines.

Limitations and Considerations

• Server requirements and compatibility: recent releases document minimum PHP and database requirements (PHP version constraints and recommended MariaDB; MySQL 8.x has known compatibility issues). Plan platform versions accordingly when deploying or upgrading.
• Third-party components: the product historically uses CKEditor in its web UI (CKEditor 4 was noted as EOL for older releases), and some legacy commercial plugins may be incompatible with newer OSS releases.
• Repository access note: attempts to fetch the Codeberg repository at the provided URL were blocked by robots.txt; documentation and release notes are available on the official site and support pages, and the b1gMailServer add-on has a referenced GitHub mirror for its server component.

b1gMail is geared toward operators who need an integrated webmail and groupware portal with administrative controls and extensibility. It is a mature product with documented installation guides, admin manuals and plugin development guidance for deploying and customizing hosted email services.
