Implementation of RFC 6352 and RFC 6764 in DNS Settings

[adiko01]

Summary

Addition of the following (optional) DNS records.

_caldavs._tcp SRV 0 1 443 calendar.example.com.
_caldavs._tcp TXT path=/SOGo/dav/
_carddavs._tcp SRV 0 1 443 addressbook.example.com.
_carddavs._tcp TXT path=/SOGo/dav/

Motivation

The above-mentioned RFCs define a standard for DNS records, which enables the automatic finding of CardDAV and CalDAV resources. This allows users to automatically find the calendars and address books on Thunderbird after setting up the email inbox and set them up with just a few clicks.

Aren't these entries already mentioned in the documentation? See: https://docs.mailcow.email/getstarted/prerequisite-dns/#the-advanced-dns-configuration

I seem to have lost a part when inserting my text.

It would be nice if these were also listed in the GUI and in the download of the zone for the domain.
In the GUI, a second tab or a menu to expand with the optional records would perhaps be practical.
