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.

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.

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.

1181: Update to address issue #1178 (HTTP headers) r=muhlemmer a=bladeswords
This change should remove the duplicate `x-xss-protection` header and also the `x-powered-by` header. Hopefully a pull request to main is appropriate, but may be worth back porting to 1.7.
Tested config by modifying live 1.7 nginx config and reloading. Has had the desired outcome of removing the headers.
```/etc/nginx # nginx -t -c /etc/nginx/nginx.conf
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
/etc/nginx # nginx -s reload
```
These steps were based on:
- https://serverfault.com/questions/928912/how-do-i-remove-a-server-added-header-from-proxied-location
- https://serverfault.com/questions/929571/overwrite-http-headers-comming-back-from-a-web-application-server-proxied-in-ngi
- http://nginx.org/en/docs/http/ngx_http_proxy_module.html#proxy_hide_header
## What type of PR?
Enhancement
## What does this PR do?
Removes duplicate and unneeded headers. See issue #1178

To facilitate this, the default redirect at / can be disabled, even if
the default remains at redirecting to the webmailer.
The extensions are within the host scope and are read from
$ROOT/overrides/nginx/*.conf.
- Specified seperated /health path in order to allow for healthcheck even if webmail and admin are not seletectd. This also allows healthchecking fom external services like DNS load balancers;
- Make curl not to fail on TLS because localhost is not included in the certificates.
Allows to use mailu without docker-compose when hostnames are not set up
by docker itself but provided via a separate resolver.
Use case: use mailu using nomad scheduler and consul resolver instead of
docker-compose. Other servers are provided by the DNS resolver that
resolves names like admin.service.consul or webmail.service.consul.
These names needs to be configurable.
