## Description

A modern, self-hosted workspace that combines email, calendars, contacts, and file storage in a single web interface. It works with existing email providers through IMAP, SMTP, AWS SES, SendGrid, Mailgun, and Postmark; syncs calendars via CalDAV with Apple Calendar, Thunderbird, DAVx⁵, and Outlook; syncs contacts via CardDAV across iOS, Android, macOS, Windows, and Linux; and provides WebDAV/S3-backed file storage with sharing. Authentication options include local accounts, Google OIDC, and generic OIDC providers. The application is API-first with a management API for provisioning. Deployment uses Docker Compose with PostgreSQL and Redis, with a minimum of 1 GB memory and one CPU core. Licensed under AGPL-3.0-or-later. Hosted versions are available at Kurrier.io and Kurrier Mail.
