Mail-in-a-Box is a self-hosted email solution that allows users to set up their own dedicated email hosting server easily. By transforming a fresh cloud computer into a fully functional mail server, it provides features similar to popular email services but with complete control over your data.
Key features include:
- **Webmail and IMAP/SMTP Support**: Access your email via Roundcube Webmail, and use IMAP/SMTP for mobile and desktop clients.
- **Contacts and Calendar Synchronization**: Integrated tools for managing contacts and calendars.
- **Spam Protection**: Includes spam filtering, greylisting, and customizable mail filter rules.
- **Automated Backups**: Supports backups to Amazon S3 and other services.
- **DNS Management**: Automatically configures DNS records for mail deliverability and security, including SPF, DKIM, DMARC, and DNSSEC.
- **Multi-User and Multi-Domain Support**: Can host email for multiple users and domains, along with simple static website hosting capabilities.
For setup, users can refer to the
setup guide and access community support through forums and chat rooms. The current version is v73, and users upgrading from earlier versions need to transition to Ubuntu 22.04.
