1380: [Roundcube] DKIM sign message delivery reports r=mergify[bot] a=TheLegend875
This PR enables the From header for message delivery reports in Roundcube.
This ensures that the message delivery report is DKIM signed and therefore not not blocked or considered spam by receiving mailservers.

1399: Remove SPF type SPF record #1394 r=mergify[bot] a=bladeswords
As mentioned in #1394 - In accordance with RFC 7208, offer only TXT RRs for SPF.
Agree with @Nebukadneza - but not sure how to go about telling people to remove the old record...
## What type of PR?
Documentation
## What does this PR do?
Removes the recommendation to add a SPF RR for SPF records, as this is no longer RFC complaint and often causes issues to maintain two records.

1389: Prefer specific alias over wildcard, regardless of case r=mergify[bot] a=Nebukadneza
## What type of PR?
bug-fix
## What does this PR do?
Since direct addresses (not aliases) are case-insensitive since a while,
it makes sense for aliases to behave the same. Up until now, a wildcard
alias could trump a alias not-matching-the-case of the incoming address.
This clarifies this behavior.
## Notes
I realize that the if-hell down there isn’t nice. What it is, however, is quite clear and easy to read. I’m hoping that if anyone ever gets confused in the future, this will make the current behavior transparent. For me, that was more important than a minimal amount of statements/branches …

want to insert empty newlines and #-commented lines in their postfix
override files too. This will now ignore such bogus-lines and not send
them to `postconf`, which produced ugly errors in the past.

1320: Add xapian full-text-search plugin to dovecot r=mergify[bot] a=Nebukadneza
## What type of PR?
Enhancement
## What does this PR do?
Currently we are not able to offer our users a FTS experience after the
demise of lucene due to unfixed coredumps with musl/alpine.
We now add lucene, the only remaining maintained small/lean FTS plugin
for dovecot. It is quite simple to add to our stack: A two-stage docker
build is used to compile the fts plugin in the first stage, and copy
over only the resulting plugin-artifact to the second stage, which is
our usual dovecot container. Configuration is also minimal.
There was a upstream issue where bodies were not able to be searched for subwords, but fortunately it was fixed quite quickly. We currently need to wait for a new release to use a stable tag in our `Dockerfile`.

1183: Fix rspamd-learn when moving mail from/to junk folder r=mergify[bot] a=Nebukadneza
Before, the ham/spam scripts got the rspamd-ip/port from the environment.
However, when checking the environment of these processes now, it seems
cleared. Maybe the new dovecot version now clears environment? — I couldn’t
find a hint.
In any case, using the common mechanism of injecting the ip/port from where
it’s definately known by the already-used jinja2-mechanism seems reasonably
safe.
## What type of PR?
bug-fix
## What does this PR do?
Instead of relying on dovecot passing our environment cleanly to sieve-called scripts, this explicitly injects the antispam ip/port into the spam/ham scripts used when moving files from/to the spam-folder. This required some management of the files, such as setting proper permissions after the jinja-run.

1084: Allow subnet with host bit set in setup r=mergify[bot] a=hoellen
## What type of PR?
bug-fix
## What does this PR do?
This allows to set the host bit in the subnet while using the [setup](https://setup.mailu.io/1.6/). The host bits are now masked out to determine the appropriate network address. This means that e.g. `172.17.0.1/12` is now considered as `172.17.0.0/12`.
So new users are not confused by error messages while setup a new Mailu instance (as you can see the multiple requests in the Matrix chat).

## What type of PR?
enhancement
## What does this PR do?
Fetchmail in alpine is ~5 years old — and doesn’t support current SSL/TLS
variants anymore. This especially leads to our own fetchmail not being able to
pull mail from mailu itself. Since no new fetchmail release is on the horizon,
let’s build the lastest distribution artifact — which strangely is not
6.4.0-snapshot, but 7.0.0-alpha — ourselves.
