1939: Ensure that we don't do multiple DNS lookups in the sieve script r=mergify[bot] a=nextgens
## What type of PR?
bug-fix
## What does this PR do?
It ensures that DNS lookups don't introduce inconsistent state. We may want to go further and actually check the return codes of rspamc too.
I haven't tested it but it should work.

1902: Make smtp_tls_policy_maps easily configurable r=mergify[bot] a=nextgens
## What type of PR?
Feature
## What does this PR do?
- Make smtp_tls_policy_maps easily configurable. This is useful to force TLS verification of specific destinations (or relays).
We should probably discuss what's on the list by default. I have found a top100 list online, ran it through a script to check all the records and found 90 destinations we could use.
- disable TLS session tickets (this reduces the PFS window from 1day to 1h)
- enable system CAs by default (to allow for OUTBOUND_TLS_LEVEL above encrypt without additional overrides)

1925: Optimize Rainloop: Change to NGINX r=mergify[bot] a=Erriez
## What type of PR?
- Reduce build time.
- Reduce image size.
- Faster user response using CGI.
## What does this PR do?
### Related issue(s)
- Mention an issue like: #1830, #1200 and #1924
- Auto close an issue like: closes#1924
## Prerequistes
Documentation updates TBD (requires some guidance):
- [ ] In case of feature or enhancement: documentation updated accordingly
- [ ] Unless it's docs or a minor change: add [changelog](https://mailu.io/master/contributors/workflow.html#changelog) entry file.
## Technical details
- Image from `php:7.4-apache` to `nginx:1.21-alpine` followed by PHP7 installation.
- Move `.ini` files to directory `defaults/`.
- Move files `sso.php and include.php` to directory `login/`.
- NGINX configuration:
- `access_log off;` as this is handled by front.
- `error_log /dev/stderr err; configured to reduce output. The logging in `start.py` is useless.
- PHP configuration optimized for CGI usage and requires a config file `config/php-rainloop.conf` -> `/etc/php7/php-fpm.d/rainloop.conf`.
- `.ini` files are parsed / substituted by `socrate` Python module.
Further optimization is possible by completely removing Python. This is only used to parse the `.ini` files and can be done via Bash scripts. This saves more build time and image size can be reduced to 112MB.
## Reviewing
This PR requires multiple reviewers and extensive testing before merging into master. Data/settings are compatible with previous images.

1922: Harden postfix's configuration r=mergify[bot] a=nextgens
## What type of PR?
enhancement
## What does this PR do?
It hardens the default configuration:
- disable AUTH commands on port 25 (nginx was not advertising the capability: normal clients wouldn't attempt it)
- fix Forward Secrecy by ensuring that we don't use session tickets and don't cache on forensically carveable mediums
- prevent clear-text credentials from being sent while authenticating to remote relays (this may break things if the relay doesn't support challenge-based authentication NOR STARTTLS - unlikely).
- switch to default RSA keysizes (2048 bits and they get rekeyed every 3 months -modern clients will do ECC)
- enable ECC certificates (much smaller than RSA keys, faster for better security margin)
- configure nginx so that it doesn't send the legacy/root CA (clients that require it are unlikely to do TLS1.2 any ways)
I don't think that any of those changes is impactful enough to warrant being documented.

1928: Change letsencrypt timer from 1h --> 1 day r=mergify[bot] a=jackmurray
There's no need to be calling certbot so frequently. Letsencrypt certificates last for 90 days so polling every hour is just wasteful. Once per day should be more than sufficient to catch any certificates before they even get close to expiring.
## What type of PR?
Enhancement
## What does this PR do?
Reduces unnecessary load on the Letsencrypt ACME servers.

Adds a 'none' env option to WEBROOT_REDIRECT so that no `location /`
configuration is written to nginx.conf.
This is useful for setting up Mailu and Mailman where we override the
root to proxy to the mailing list server instead. Without this change
the nginx container will not start, or for 1.7 users can set their
WEBMAIL_PATH to / with no webmail to get the same results.
This fix means that future users don't have to choose between webmail
and a root override and makes the configuration intention clear.
I have found a list of the top100 email destinations online and ran them
through a script to ensure that all of their MX servers had valid
configuration... this is the result
encrypt means "ensure we have some confidentiality" whereas secure means
"ensure we have confidentiality while talking to the right peer"
(protects against passive or/and active MITM attacks)
