ghcr.io/lanqin996/lanqin-emailWhat is LanQin Email?
This self-hosted mail system gives you a modern webmail interface with multi-mailbox support, rich-text editing, scheduled sending, contacts, signatures, and inbox rules. Administrators manage domains, DKIM keys, DNS records, mailboxes, aliases, users, and permission groups with quotas for attachment size, send rates, and mailbox counts. The integrated mail stack runs Postfix for SMTP, Dovecot for IMAP/POP3, and Rspamd for spam filtering and DKIM signing. Deployment is a single Docker container with SQLite (or MySQL/PostgreSQL), plus a multi-container option for debugging. Features include Linux.do OAuth2 SSO, TOTP 2FA, Cloudflare Turnstile, invitation codes, external IMAP aggregation with Gmail/Outlook OAuth2, and an Open API with webhooks. Licensed under GPL-3.0-only.
