What Mailbirch is
Mailbirch is a small, independent email service running on its own hardware. There is no third-party mail relay in the path: mail arriving at mailbirch.com is accepted, filtered and stored by servers we operate, and mail you send leaves from the same place.
What an account includes
| Mailbox storage | 2 GB |
|---|---|
| Addresses | One primary address plus up to five aliases delivering into the same inbox |
| Access | Web client, plus IMAP and SMTP for any mail application |
| Security | TLS on every connection, optional two-factor authentication with recovery codes |
| Outgoing mail | DKIM-signed, SPF-aligned, DMARC-reported; 200 recipients per day |
| Price | Free — the site carries advertising instead |
Why aliases matter
Most spam starts with a leak at the other end: a shop, a forum or a giveaway loses its address list. Give each of them a separate alias and a leak tells you exactly who lost it. Delete that alias and the flow stops, while your real address stays untouched. All five aliases arrive in one inbox, so there is nothing extra to check.
How mail is protected
Incoming messages are scored before they reach the inbox, so forged “your account is suspended” notices land in Junk. Remote images are held back until you ask for them, which means opening a message does not tell the sender that you read it. Outgoing mail is signed so that nobody can send messages wearing your domain name. The full picture is on the security page.
Getting an address
Public sign-up is closed at the moment; addresses are issued by the administrator. Write to postmaster@mailbirch.com and one will be created for you. If you already have an address, sign in — and if you would rather use your own mail application, the settings are here.
What runs underneath
Postfix handles SMTP, Dovecot stores and serves the mail over IMAP, rspamd scores incoming messages and signs outgoing ones, and PostgreSQL holds the account directory. Certificates come from Let's Encrypt and renew automatically. Nothing about your messages is scanned to target advertising.
