If an app registers the sender address _app@doma.in_ **and** a yunohost account configured an alias for the same address the app will not be able to send emails anymore.
postfix asks the first map defined in smtpd_sender_login_maps and finds that the address _app@doma.in_ can be used as a sender address by the yunohost account having configured the alias and **then stops and doesn't look up the second list** for registered apps.
The unionmap instructs postfix to join a list from both sources and then return the match from that joined list which would then contain _yunohost_account_having_registered_alias, appname_ for the lookup of _app@doma.in_.
This allows the yunohost account having registered the alias and the app being registered to use the sender address to send email using that sender **and makes it possible to receive replies to the emails going out from the app**.

tells dovecot to create standard folders on first login if they do not exist and which folder names are used for special purposes like archive, spam/junk, sent, etc.
For rspamd being able to learn ham or spam from messages being moved into spam/junk folders or out of them dovecot needs to know how spam/junk folders and trash folders are named.
The former rules narrowed the folders being recognized as spam/trash down to just 'Junk, SPAM, Trash' (case-senistive).
Since users and admins can change the foldernames and write their own seive filters to use those folders I think it is a big improvement if more folders will be recognized.
The change is supposed to accept some more commonly used folder names for spam and trash in a case-insensitive manner.
Chromium fails to load a jitsi video conference, refusing to create a
worker because it violates the Content Security Policy directive:
"script-src https: data: 'unsafe-inline' 'unsafe-eval'".
This is reasonably important for the performance of clients such as Delta Chat. The plugins are bundled with dovecot by default (see https://wiki2.dovecot.org/Plugins ) so this should not be disruptive.
in order to prevent those

Add the `wss:` field so that Nginx does not create warning when using Websocket over TLS.
This modification only affects the `Report-Only` part of the CSP, that takes care of creating warnings in the logs.
Warning ex (fr only sorry):
```
Content Security Policy: Les paramètres de la page ont empêché le chargement d’une ressource à wss://your.website.tld (« default-src »). Un rapport CSP est en cours d’envoi.
