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.
