BeaverMail Server

Run your own mail server: email for your domains, with security and spam filtering built in.

Early release. Best suited to small setups: one server, a few domains and users. Settings may still change in future updates.

Everything comes in one program for Debian and Ubuntu: sending and receiving mail, secure connections, spam filtering, and a web console to manage your domains, mailboxes and customers. It runs on your server and never contacts us.

Features

• Works with any mail app: the BeaverMail desktop app or any other app that supports IMAP and SMTP.
• Secure by default: free certificates from Let's Encrypt, set up automatically; encrypted connections; signed outgoing mail.
• Clean inboxes: checks that incoming mail really comes from its sender, and filters spam.
• Abuse protection: limits on connections, logins and sending.
• Several domains and customers: domains, mailboxes, aliases and quotas, managed from the web console or an API.
• Easy to move in: import your existing mail.

Not included yet: webmail, calendar and contacts. Use a mail app to read your mail.

Privacy

BeaverMail Server sends nothing to us: no telemetry, no update checks. It only makes the connections that delivering mail needs, and uses spam blocklists only if you turn them on.

Install

Install it from our APT repository (apt.beavermail.dev) or download it from the download page. The setup guide is in the source repository.

You will need:

• a Linux server (64-bit Intel or AMD) with a fixed IP address;
• a domain you control: BeaverMail Server tells you which DNS records to add;
• a hosting provider that allows outgoing mail, or a relay to send through.
