Per requested changes added the ``DEFAULT_SPAM_THRESHOLD`` to the main
application configuration dictionary in ``configuration.py`` and updated
``models.py`` accordingly.
No error handling is added, as that was not required.
This commit adds functionality to set a custom default spam threshold
for new users. The environment variable ``DEFAULT_SPAM_THRESHOLD`` can
be used for this purpose. When not set, it defaults back to 80%, as the
default value was before
If ``DEFAULT_SPAM_THRESHOLD`` is set to a value that Python cannot
parse as an integer, a ValueError is thrown. There is no error handling
for that case built-in.

2276: Autoconfig of email clients r=mergify[bot] a=nextgens
## What type of PR?
Feature
## What does this PR do?
It provides auto-configuration templates for email clients and encourages them to use implicit TLS (see https://nostarttls.secvuln.info/)
There are numerous caveats:
- it will only work if suitable DNS records are created and certificates obtained (autoconfig, autodiscover, ...)
- the mobileconfig file isn't signed
- the credentials will be prompted... we could/should provision a token on each request instead
- it currently doesn't advertise caldav
- it's IMAP only

Ensure we send ISRG_X1 in the handshake on port 25 (non-interactive, size doesn't really matter).
Update the DANE pin to reflect the change.
I am not sure whether we will need to add --preferred-chain= in the future; This may be the case when letsencrypt decides to use X2/the ECDSA chain
This needs to be tested on a letsencrypt account that isn't mine (I'm opted in for the alternate cert chains)

2058: Implement versioning for CI/CD workflow. r=mergify[bot] a=Diman0
## What type of PR?
Feature!
## What does this PR do?
This PR introduces 3 things
- Add versioning (tagging) for branch x.y (1.8). E.g. 1.8.0, 1.8.1 etc.
- docker repo will contain x.y (latest) and x.y.z (pinned version) images.
- The X.Y.Z tag is incremented automatically. E.g. if 1.8.0 already exists, then the next merge on 1.8 will result in the new tag 1.8.1 being used.
- Make the version available in the image.
- For X.Y and X.Y.Z write the version (X.Y.Z) into /version on the image and add a label with version=X.Y.Z
- This means that the latest X.Y image shows the pinned version (X.Y.Z e.g. 1.8.1) it was based on. Via the tag X.Y.Z you can see the commit hash that triggered the built.
- For master write the commit hash into /version on the image and add a label with version={commit hash}
- Automatic releases. For x.y triggered builts (e.g. merge on 1.9) do a new github release for the pinned x.y.z (e.g. 1.9.2).
- Release shows a static message (see RELEASE_TEMPLATE.md) that explains how to reach the newsfragments folder and change the branch to the tag (x.y.z) mentioned in the release. Now you can get the changelog by reading all newsfragment files in this folder.
This PR does not change anything to our workflow (what we (human persons) do). Our processes are still exactly the same. The above introduced logic is automatic. When we backport to X.Y all the magic for creating the pinned version X.Y.Z is handled by the CI/CD workflow.

## Testing
Suggested testing steps. This should cover all situations including BORS. It does require that you use your own docker repo or temporarily create a new one.
Suggested testing steps.
1. Create new github repo.
2. Add the required docker secrets to the project (see beginning of CI.yml for the secret names), DOCKER_UN, DOCKER_PW, DOCKER_ORG, DOCKER_ORG_TESTS.
3. Clone the project.
4. Copy the contents of the PR to the cloned project.
5. Push to your new github repo.
6. Now master images are built. Check that images with tag master are pushed to your docker repo
7. Check with docker inspect nginx:master that it has the label version={commit hash}.
8. Run an image, run `docker-compose exec <name> cat /version`. Note that /version also contains the pinned version. For master the pinned version is the commit hash.
9. Create branch 1.8.
10. Push branch 1.8 to repo.
11. Note that tags 1.8 and 1.8.0 are built and pushed to docker repo
12. Inspect label and /version. Note that 1.8 and 1.8.0 both show version 1.8.0.
13. Push another commit to branch 1.8.
14. Note that tags 1.8 and 1.8.1 are built and pushed to docker repo
15. Inspect label and /version. Note that 1.8 and 1.8.1 both show version 1.8.1.
16. Let's check BORS stuff.
17. Create branch testing.
18. Push the commit with the exact commit text (IMPORTANT!!): `Try #1234:`'.
19. Note that images are built and pushed for tag `pr-1234`.
20. Inspect label and /version. Note that the version is `pr-1234`.
20. Create branch staging.
21. Push the commit with commit text: `Merge #1234`.
22. Note that this image is not pushed to docker (as expected).

signing failure: cannot request data from the vault url: /internal/rspamd/vault/v1/dkim/ ...
this is working fine, but introduces a sqlalchemy warning
when using config-import:

replacing it with newly flushed object.
Are there load operations occurring inside of an event handler

ConfigManager should not replace app.config - this is causing trouble

1987: Enhancement to the rate limits r=mergify[bot] a=nextgens
## What type of PR?
enhancement
## What does this PR do?
Turn the rate-limiters into something useful (that won't fire for no reason).
- fix rate-limiting on /webdav/
- it changes the rate-limiting behaviour from limiting a single IP address to a subnet of a reasonable size (/24 on v4 and /56 on v6 both are now configurable) : AUTH_RATELIMIT_IP / AUTH_RATELIMIT_IP_V4_MASK / AUTH_RATELIMIT_IP_V6_MASK
- It ensures we only use IP-based rate-limits for attempts on accounts that do not exist
- it creates a new rate limit preventing attackers from targetting a specific user account (separate from what's above) : AUTH_RATELIMIT_USER
- it introduces a rate limiting exemption mechanism whereby, upon authentication, users will see their source-ip address being exempt for a specific amount of time AUTH_RATELIMIT_EXEMPTION_LENGTH. A similar mechanism is available for web-based sessions (see below)
- It introduces in AUTH_RATELIMIT_EXEMPTION a comma separated list of network CIDRs that will be exempt from both types of rate limiting
- it implements device-tokens, as described on https://owasp.org/www-community/Slow_Down_Online_Guessing_Attacks_with_Device_Cookies to ensure that genuine users aren't locked-out by a malicious attacker abusing the rate-limit feature.
Things that could be improved include:
- the IP-based rate limiter flags attempts against "non-existing" accounts: it could go further and flag the number of unique non-existing accounts attempted (to prevent the case of a user making a typo in his MUA configuration)
- the IP address exemption mechanism doesn't pin the exemption to a specific username: any real user can trivially bypass the rate limits (and attempt to brute-force someone else's account)

2017: rspamd: get dkim keys via REST API instead of filesystem r=mergify[bot] a=ghostwheel42
## What type of PR?
enhancement
## What does this PR do?
rspamd now uses hashicorp's vault api v1 to get dkim keys and selectors for a domain.
this allows future enhancement (multiple keys) without reconfiguring and restarting rspamd.
it also makes mounting the /dkim volume into the rspamd container unnecessary.
### Related issue(s)
- improves and closes#2012
- allows to implement key rotation using multiple selectors (see #1700)
- allows to implement dkim for alternate domains (see #1519)
- fixes and closes#1345 (selector transmitted by admin container is used)
- closes#1179 (no keys on disk)
- allows to implement key rotation from the outside (ie. via a helper script talking to some dns provider's api) (see #547)
