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.

1656: Add ability to set no WEBROOT_REDIRECT to Nginx r=mergify[bot] a=DavidFair

## What type of PR?

Enhancement / Documentation

## What does this PR do?

From commit:

---

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've also added bullet points to break up a long flowing sentence in `configuration.rst` - it should be a bit easier to read now

1754: centralize Webmail authentication behind the admin panel (SSO) r=mergify[bot] a=nextgens

## What type of PR?

Enhancement: it centralizes the authentication of webmails to the admin interface.

## What does this PR do?

It implements the glue required for webmails to do SSO using the admin interface.
One of the main advantages of centralizing things this way is that it reduces significantly the attack surface available to an unauthenticated attacker (no webmail access until there is a valid Flask session).

Others include the ability to implement 2FA down the line and rate-limit things as required.

## What type of PR?

Feature: it implements a credential cache to speedup authentication requests.

## What does this PR do?

Credentials are stored in cold-storage using a slow, salted/iterated hash function to prevent offline bruteforce attacks. This creates a performance bottleneck for no valid reason (see the
rationale/long version on https://github.com/Mailu/Mailu/issues/1194#issuecomment-762115549).

The new credential cache makes things fast again.

This is the simpler version of  (with no new dependencies)

1776: optimize generation of transport nexthop r=mergify[bot] a=ghostwheel42

## What type of PR?

bug-fix and enhancement.

## What does this PR do?

Possibly there should be more input validation when editing a relay, but for now this tries to make the best out of the existing "smtp" attribute while maintaining backwards compatibility. When relay is empty, the transport's nexthop is the MX of the relayed domain to fix  

```
RELAY			NEXTHOP						TRANSPORT
empty			use MX of relay domain				smtp:domain
:port			use MX of relay domain and use port	smtp:domain:port
target			resolve A/AAAA of target			smtp:[target]
target:port		resolve A/AAAA of target and use port	smtp:[target]:port
mx:target		resolve MX of target				smtp:target
mx:target:port	resolve MX of target and use port	smtp:target:port
lmtp:target		resolve A/AAAA of target			lmtp:target
lmtp:target:port	resolve A/AAAA of target and use port	lmtp:target:port

target can also be an IPv4 or IPv6 address (an IPv6 address must be enclosed in []: [2001:DB8::]).
```

When there is proper input validation and existing database entries are migrated this function can be made much shorter again.

1610: add option to enforce inbound starttls r=mergify[bot] a=lub

## What type of PR?

Feature

## What does this PR do?
It implements a check in the auth_http handler to check for Auth-SSL == on and otherwise returns a 530 starttls error.
If INBOUND_TLS_ENFORCE is not set the behaviour is still the same as before, so existing installations should be unaffected.

Although there is a small difference to e.g. smtpd_tls_security_level of Postfix.

Postfix already throws a 530 after mail from, but this solution only throws it after rcpt to. auth_http is only the request after rcpt to, so it's not possible to do it earlier.

### Related issue(s)
 is kinda related, although this PR doesn't solve the issue that the headers will still display ESMTP instead of ESMTPS

1765: Set sensible cookie flags on the admin app r=mergify[bot] a=nextgens

## What type of PR?

Bugfix

## What does this PR do?

It sets the right flags on the session cookie issued by the admin app.
This should probably be backported as the lack of secure flag on TLS-enabled setup is a high risk vulnerability.

SameSite is hardening / helps against CSRF on modern browsers
HTTPOnly is hardening / helps reduce the impact of XSS

1618: add OCSP stapling to nginx.conf r=mergify[bot] a=lub

It's not added in tls.conf, because apparently the mail ssl module
doesnt' support OCSP stapling.

https://nginx.org/en/docs/http/ngx_http_ssl_module.html#ssl_stapling
^ exists

https://nginx.org/en/docs/mail/ngx_mail_ssl_module.html#ssl_stapling
^ missing

When the configured certificate doesn't have OCSP information, it'll
just log a warning during startup.

## What type of PR?

enhancement

## What does this PR do?

It enables OCSP stapling for the http server. OCSP stapling reduces roundtrips for the client and reduces load on OCSP responders.

## What does this PR do?

This PR enables usage of DB_PW_FILE and SECRET_KEY_FILE instead of DB_PW and SECRET_KEY to load these values from files instead of supplying them directly. That way it's possible to use Docker secrets.

Dario Ernst b6716f0d74 Remove "CHUNKING" capability from nginx-smtp
With `CHUNKING`set as a capability, nginx advertises this capability to
clients at a stage where the SMTP dialog does not seem to be forwarded
to the proxy-target (postfix) yet. Nginx' SMTP parser itself does not
support the `BDAT` command issued as part of a chunke-d dialog. This makes
Nginx respond with a `250 2.0.0 OK` and close the connection, after the
mail-data got sent by the client — without forwarding this to the
proxy-target.

With this, users mail can be lost.

Furthermore, when a user uses a sieve filter to forward mail, dovecot
sometimes chunks the forwarded mail when sending it through `front`.
These forwards then fail.

Removing `CHUNKING` from the capabilities fixes this behavior.
