WildDuck
A Node.js IMAP/POP3 and HTTP API server backed by MongoDB and Redis. A complete SMTP suite adds inbound Haraka and outbound ZoneMTA; the standalone image is not that entire suite.
Start with the first guide, then choose a sending, receiving, or feedback task. Each walkthrough identifies permissions, operational checks, and the boundary between the service and MailKite. Refer to the official WildDuck documentation for current platform requirements.
Explore the guides
Choose a WildDuck standalone or full mail-suite deployment
Distinguish the IMAP/POP3/API server from its SMTP integrations and persist MongoDB, Redis, and attachment storage deliberately.
Secure WildDuck management API and mailbox access
Provision through the documented REST interface and distinguish administrative tokens, user credentials, and application-specific passwords.
Plan WildDuck mail-suite backup and recovery
Recover authoritative database and attachment data with compatible SMTP integration state instead of backing up only stateless application containers.
