Run an Anonymous Email Service on Tor

Mainstream email providers like Gmail, Outlook, and Yahoo collect vast amounts of metadata: sender and recipient addresses, timestamps, IP addresses, subject lines, and even message content for advertising. Even privacy-focused providers like ProtonMail or Tutanota operate on the clearnet and must respond to legal requests from their jurisdictions.

• Complete metadata protection — Tor hides sender and recipient IP addresses from network observers
• No real identity required — Users can create accounts with pseudonyms, no phone verification
• Server location hidden — Your mail server's physical location is protected by the .onion address
• Jurisdiction choice — Choose offshore hosting in privacy-friendly countries

Self-hosted email on Tor is the strongest form of email privacy available today.

AnubizHost supports deployment of robust email server software configured for .onion access:

• Postfix + Dovecot — The industry-standard combination for SMTP delivery and IMAP/POP3 mailbox access. We configure both to accept connections exclusively over Tor.
• Mail-in-a-Box — An all-in-one email solution that sets up Postfix, Dovecot, spam filtering, and webmail automatically. Modified for Tor-only operation.
• Roundcube / RainLoop — Web-based email clients accessible through Tor Browser. Provide familiar email interfaces without requiring local email client configuration.
• Custom MTA solutions — Deploy any mail transfer agent that supports SMTP. Our Tor hosting handles the hidden service networking layer.

All email deployments include GPG integration for end-to-end encryption and SPF/DKIM/DMARC configuration for outbound emails to clearnet addresses (via Tor exit nodes).

Running an email service on Tor involves unique operational challenges that AnubizHost helps you navigate:

• Onion-to-onion delivery — Direct email delivery between .onion addresses stays entirely within the Tor network, providing maximum privacy
• Clearnet bridging — For sending emails to Gmail, Outlook, etc., traffic exits through Tor exit nodes. We configure proper SMTP relay and reputation management.
• Spam prevention — SpamAssassin and Rspamd are pre-configured to filter inbound spam without compromising privacy
• Storage encryption — All mailboxes are stored on LUKS-encrypted disks with per-user encryption available
• Backup strategy — Automated encrypted backups ensure mail data is recoverable without exposing plaintext

We recommend limiting clearnet email delivery and encouraging users to communicate .onion-to-.onion for maximum anonymity.
