Mail-in-a-Box v0.50 Release Notes

Release Date: 2020-09-25 // over 3 years ago

  • Setup:

    • ⬆️ When upgrading from versions before v0.40, setup will now warn that ownCloud/Nextcloud data cannot be migrated rather than failing the installation.

    Mail:

    • An MTA-STS policy for incoming mail is now published (in DNS and over HTTPS) when the primary hostname and email address domain both have a signed TLS certificate installed, allowing senders to know that an encrypted connection should be enforced.
    • The per-IP connection limit to the IMAP server has been doubled to allow more devices to connect at once, especially with multiple users behind a NAT.

    DNS:

    • autoconfig and autodiscover subdomains and CalDAV/CardDAV SRV records are no longer generated for domains that don't have user accounts since they are unnecessary.
    • IPv6 addresses can now be specified for secondary DNS nameservers in the control panel.

    TLS:

    • TLS certificates are now provisioned in groups by parent domain to limit easy domain enumeration and make provisioning more resilient to errors for particular domains.

    Control Panel:

    • 📄 The control panel API is now fully documented at https://mailinabox.email/api-docs.html.
    • 👉 User passwords can now have spaces.
    • 🚚 Status checks for automatic subdomains have been moved into the section for the parent domain.
    • 🛠 Typo fixed.

    🌐 Web:

    • 0️⃣ The default web page served on fresh installations now adds the noindex meta tag.
    • The HSTS header is revised to also be sent on non-success responses.
