|

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.
|
||||
* 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.
|
||||
* MTA-STS reporting is enabled with reports sent to administrator@ the primary hostname.
|
||||
* 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:
|
||||
|
||||
* 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.
|
||||
|
||||
v0.47 (July 29, 2020)
|
||||
---------------------
|
||||
|
||||
Security fixes:
|
||||
|
||||
* Roundcube is updated to version 1.4.7 fixing a cross-site scripting (XSS) vulnerability with HTML messages with malicious svg/namespace (CVE-2020-15562) (https://roundcube.net/news/2020/07/05/security-updates-1.4.7-1.3.14-and-1.2.11).
|
||||
* SSH connections are now rate-limited at the firewall level (in addition to fail2ban).
