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.

1758: Implement a simpler credential cache (alternative to #1755) r=mergify[bot] a=nextgens
## 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 #1755 (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#1588
```
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.

- the session key is now generated using
- a hash of the uid seeded by the apps secret_key (size: SESSION_KEY_BITS)
- a random token (size: 128 bits)
- the session's creation time (size: 32 bits)
- redis server side sessions are now refreshed after 1/2 the session lifetime
even if not modified
- the cookie is also updated if necessary
This can be used to delete all sessions belonging to a user/login.
For no it just iterates over all sessions.
This could be enhanced by using a prefix for and deleting by prefix.
- call cleanup_sessions on first kvstore access
this allows to run cmdline actions without redis (and makes it faster)
- Allow development using DictStore by setting REDIS_ADDRESS to the empty string in env

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.

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.
- yaml-import is now logged via schema.Logger
- iremoved relative imports - not used in other mailu modules
- removed develepment comments
- added Mailconfig.check method to check for duplicate domain names
- converted .format() to .format_map() where possible
- switched to yaml multiline dump for dkim_key
- converted dkim_key import from regex to string functions
- automatically unhide/unexclude explicitly specified attributes on dump
- use field order when loading to stabilize import
- fail when using 'hash_password' without 'password'
- fixed logging of dkim_key
- fixed pruning and deleting of lists
- modified error messages
- added debug flag and two verbosity levels
- idna.encode does not encode upper-case letters,
so .lower() has to be called on value not on result
- split email-address on '@' only once
- converted '*'.format(*) to f-strings
- added docstrings
- removed from_dict method
- code cleanup/style (list concat, exceptions, return&else, line-length)
- added TODO comments on possible future changes
- revived original config-update function for backwards compability
- renamed config-dump to config-export to be in line with config-import
- converted '*'.format(*) to f-strings
- converted string-concatenation to f-strings
renamed single letter variables (m => match)
renamed classmethod arguments to cls (model)
removed shadowing of variables (hash, context)
shortened unneeded lambda functions (id)
converted type ... is to isinstance(...)
removed unneded imports (flask)
Updated ConfigManager to only modify app.config and not replace it.
Swagger does not play well, when app.config is not a real dict and
it is not necessary to keep ConfigManager around after init.
Also added "API" flag to config (default: disabled).

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.

Because basically every MTA out there uses opportunistic TLS _in
the best case_, it's actually counter productive to use such strict
settings.
The alternative to a handshake error is often an unencrypted submission,
which is basically the opposite of what strict ssl_protocols and
ssl_ciphers tries to achieve.
Even big and established providers like Amazon SES are incompatible with the current
settings.
This reverts commit 2ddf46ad2b.
this enables usage of e.g. docker swarm secrets instead of exposing the
passwords directly via environment variables
just use DB_PW_FILE and SECRET_KEY_FILE instead of DB_PW and SECRET_KEY

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 …
