v0.50
v0.50 (September 25, 2020) -------------------------- 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: * 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.

Note that while we want everything to "just work," we can't control the rest of the Internet. Other mail services might block or spam-filter email sent from your Mail-in-a-Box.

This is a challenge faced by everyone who runs their own mail server, with or without Mail-in-a-Box. See our discussion forum for tips about that.
