v0.52 (January 31, 2021)
------------------------
Software updates:
* Upgraded Roundcube to version 1.4.10.
* Upgraded zpush to 2.6.1.
Mail:
* Incoming emails with SPF/DKIM/DMARC failures now get a higher spam score, and these messages are more likely to appear in the junk folder, since they are often spam/phishing.
* Fixed the MTA-STS policy file's line endings.
Control panel:
* A new Download button in the control panel's External DNS page can be used to download the required DNS records in zonefile format.
* Fixed the problem when the control panel would report DNS entries as Not Set by increasing a bind query limit.
* Fixed a control panel startup bug on some systems.
* Improved an error message on a DNS lookup timeout.
* A typo was fixed.
DNS:
* The TTL for NS records has been increased to 1 day to comply with some registrar requirements.
System:
* Nextcloud's photos, dashboard, and activity apps are disabled since we only support contacts and calendar.
