Add DNS DAV registring
Regarding https://tools.ietf.org/html/rfc6764 and this tutorial https://www.mailenable.com/kb/content/article.asp?ID=ME020559 : it could be great to add for every DAV server embeded app (Nxtcloud, SOGo, etc..) the registery of DNS DAV indication.

This is interesting. Do webdav clients automatically pick these up? It's the first time I am hearing of these DNS records.
@girish Yeah, by example the android client can retrieve it automatically.

Glad I found this. For reference, I set up the following records for a standard Cloudron install with active E-Mail handling and Nextcloud dealing with Card- and CalDAV.
TXT _caldavs._tcp.cloud.$DOMAIN "path=/remote.php/dav" TXT _carddavs._tcp.cloud.$DOMAIN "path=/remote.php/dav" SRV _sieve._tcp.$DOMAIN my.$DOMAIN - PORT 4190 SRV _autodiscover._tcp.$DOMAIN my.$DOMAIN - PORT 443 CNAME autodiscover.$DOMAIN - my.$DOMAIN. SRV _carddavs._tcp.$DOMAIN cloud.$DOMAIN - PORT 443 SRV _carddav._tcp.$DOMAIN cloud.$DOMAIN - PORT 80 SRV _caldav._tcp.$DOMAIN cloud.$DOMAIN - PORT 80 SRV _caldavs._tcp.$DOMAIN cloud.$DOMAIN - PORT 443 SRV _submission._tcp.$DOMAIN my.$DOMAIN - PORT 587 SRV _imaps._tcp.$DOMAIN my.$DOMAIN - PORT 993
- _submission._tcp, _imaps._tcp, _autodiscover._tcp (as well as autodiscover CNAME) and _sieve._tcp are valid for any installation where E-Mail for a domain is handled by Cloudron. These records help clients (Thunderbird, Smartphone Mail Apps, etc) to automatically discover the correct IMAP/SMTP Hostnames + Ports. In most cases, with these records set you can have Thunderbird automatically configure your Mailaccount by simply giving the mail address (e.g. firstname.lastname@example.org)
- _carddav*/_caldav* SRV Records should be set by the respective Apps dealing with the protocols (Sogo, Nextcloud, etc) as the redirection should be pointed to the App's subdomain
- _caldavs/_carddavs* TXT Records should also be set by the respective Apps, as they instruct DAV clients where to find the concrete path DAV-Requests are handled (does the same as .well_known on the webserver; according to some docs and posts in the internet, these records (SRV+TXT) are required for MacOS/iOS clients to correctly discover and connect)
There are certainly more things that can be done with this. In general, this is a massive UX plus. DavDroid and Thunderbird both are able to automatically connect and discover everything needed by simply providing the $USER@$DOMAIN E-Mail adress during account setup. Will test more clients today, but I'm sure many follow these standards.
