Fixed postfix not logging to standard out.
Fixed not all containers logging to journald.
Removed POSTFIX_LOG_FILE functionality. Added documentation on how to achieve the same (log to file) via journald & rsyslogd (see new FAQ entry 'How can I view and export the logs of a Mailu container?').
2613: Enhance network segregation r=nextgens a=nextgens
## What type of PR?
enhancement
## What does this PR do?
- put radicale and webmail on their own network: this is done for security: that way they have no privileged access anywhere (no access to redis, no access to XCLIENT, ...)
- remove the EXPOSE statements from the dockerfiles. These ports are for internal comms and are not meant to be exposed in any way to the outside world.

This is not perfect...
- dovecot now complains about waitpid/finding a new process
- postfix is still regularly pinging rspamd / his milter and that
generates a few lines worth of logs each time.
2479: Rework the anti-spoofing rule r=mergify[bot] a=nextgens
## What type of PR?
Feature
## What does this PR do?
We shouldn't assume that Mailu is the only MTA allowed to send emails on behalf of the domains it hosts.
We should also ensure that it's non-trivial for email-spoofing of hosted domains to happen
Previously we were preventing any spoofing of the envelope from; Now we are preventing spoofing of both the envelope from and the header from unless some form of authentication passes (is a RELAYHOST, SPF, DKIM, ARC)

- The main workflow file has been optimised and simplified.
- Images are built in parallel when building locally resulting in faster build times.
- The github action workflow is about 50% faster.
- Arm images are built as well. These images are not tested due to restrictions of github actions (no arm runners). The tags of the images have -arm appended to it.
- Arm images can also be built locally.
- Reusable workflow is introduced for building, testing and deploying the images.
This allows the workflow to be reused for other purposes in the future.
- Workflow can be manually triggered. This allows forked Mailu projects to also use the workflow for building images.
2325: postfix: wrap IPv6 CIDRs in square brackets for RELAYNETS r=mergify[bot] a=pommi
## What type of PR?
bug-fix
## What does this PR do?
This PR wraps IPv6 CIDRs in the `RELAYNETS` environment variable in square brackets for the postfix configuration.
The `RELAYNETS` environment variable is used for configuring both postfix `mynetworks` and rspamd `local_networks`. Postfix requires IPv6 addresses to be wrapped in square brackets (eg. `[2001:db8::]/64`).
When an IPv6 address is not wrapped in square brackets in the postfix configuration for `mynetworks` it results in this error while processing an incoming email from an IPv6 sender:
```
postfix/smtpd[340]: warning: 2001:db8::/64 is unavailable. unsupported dictionary type: 2001
postfix/smtpd[340]: warning: smtpd_client_event_limit_exceptions: 2001:db8::/64: table lookup problem
```
The sender sees an error and the incoming email is refused:
```
451 4.3.0 <unknown[2001:xxx:xxx:xxx:xxx:xxx:xxx:xxx]>: Temporary lookup failure
```
I tried to work around this issue by wrapping the IPv6 CIDR in square brackets in the `RELAYNETS` environment variable, but it segfaults rspamd, because it can't deal with this non-standard IPv6 notation used by postfix:
```
kernel: [4305632.603704] rspamd[1954299]: segfault at 0 ip 00007fb848983871 sp 00007ffe02cc6d1
8 error 4 in ld-musl-x86_64.so.1[7fb848948000+48000]
```

2323: Fix Postfix FileExistsError on startup r=mergify[bot] a=Pumba98
## What type of PR?
bug-fix
## What does this PR do?
I'm running mailu with the mailu helm-chart on kubernetes. Sometimes when a Pod restarts I get the following error during startup:
```
Process Process-1:
Traceback (most recent call last):
File "/usr/lib/python3.9/multiprocessing/process.py", line 315, in _bootstrap
self.run()
File "/usr/lib/python3.9/multiprocessing/process.py", line 108, in run
self._target(*self._args, **self._kwargs)
File "/start.py", line 18, in start_podop
os.mkdir('/dev/shm/postfix',mode=0o700)
FileExistsError: [Errno 17] File exists: '/dev/shm/postfix'
INFO:MAIN:MTA-STS daemon starting...
```
But that does not prevent the container startup. When mails arrive it will fail with something like:
```
postfix/trivial-rewrite[94979]: warning: connect to /tmp/podop.socket: No such file or directory
postfix/trivial-rewrite[94979]: warning: table socketmap:unix:/tmp/podop.socket:transport lookup error: No such file or directory
postfix/trivial-rewrite[94979]: warning: socketmap:unix:/tmp/podop.socket:transport lookup error for "*"
```
I'm running this quick fix now since almost two months without problems. Maybe you got a better approach how to solve this, but this works fine for me.
