Pro Edition
The Pro edition embeds a read-only IMAP server, so standard mail clients — Thunderbird, Outlook, Apple Mail, or any IMAP library — can browse the archive directly without the WebUI.
Key facts
- Read-only: clients can list mailboxes, fetch messages, and search; nothing can modify or delete archived data
- Stable per-mailbox UIDs (persisted in a dedicated store), so incremental clients never re-download or miss messages across reconnects
- Off by default — enable with
BICHON_ENABLE_IMAP
Configuration
| Setting | Default | Description |

Access is permission-checked: connecting users see exactly the accounts their roles authorize. Login requires an active Pro license; when the license lapses, existing authenticated sessions keep their view but new logins are refused until the server restarts with a valid license.
