+# In unoptimised builds tokio tends to use a lot of stack space when
+# creating some complicated futures, tokio has an open issue for this:
+# https://github.com/tokio-rs/tokio/issues/2055.  Some of our tests
+# manage to not fit in the default 2MiB stack anymore due to this, so
+# while the issue is not resolved we want to work around this.
+# Because compiling optimised builds takes a very long time we prefer
+# to avoid that.  Setting this environment variable ensures that when
+# invoking `cargo test` threads are allowed to have a large enough
+# stack size without needing to use an optimised build.

+
+
+- Rust: Introduce a ContextBuilder #3698
+
+### Changes
+- allow sender timestamp to be in the future, but not too much
+- Disable the new "Authentication-Results/DKIM checking" security feature
+  until we have tested it a bit #3728

+  - remove relative file dependency to it from `deltachat-node` (because it did not work anyway and broke the nix build of desktop)
+  - ci: add github ci action to upload it to our download server automaticaly on realease
+

+# Delta Chat RPC python client
+
+RPC client connects to standalone Delta Chat RPC server `deltachat-rpc-server`
+and provides asynchronous interface to it.
+
+## Getting started
+
+To use Delta Chat RPC client, first build a `deltachat-rpc-server` with `cargo build -p deltachat-rpc-server`.
+Install it anywhere in your `PATH`.
+
+## Testing
+
+1. Build `deltachat-rpc-server` with `cargo build -p deltachat-rpc-server`.
+2. Run `PATH="../target/debug:$PATH" tox`.
+
+Additional arguments to `tox` are passed to pytest, e.g. `tox -- -s` does not capture test output.
+
+## Using in REPL
+
+Setup a development environment:
+```
+$ tox --devenv env
+$ . env/bin/activate
+```
+
+It is recommended to use IPython, because it supports using `await` directly
+from the REPL.
+
+```
+$ pip install ipython
+$ PATH="../target/debug:$PATH" ipython
+...
+In [1]: from deltachat_rpc_client import *

+In [5]: system_info = await dc.get_system_info()
+In [6]: system_info["level"]
+Out[6]: 'awesome'
+In [7]: await rpc.close()
+```

+///
+/// After having checked DKIM, our email server adds an Authentication-Results header.

+/// in order to make us think that DKIM was correct in their From-forged email.
+///
+/// In order to prevent this, each email server adds its authserv-id to the
+/// Authentication-Results header, e.g. Testrun's authserv-id is `testrun.org`, Gmail's
+/// is `mx.google.com`. When Testrun gets a mail delivered from outside, it will then
+/// remove any Authentication-Results headers whose authserv-id is also `testrun.org`.
+///
+/// We need to somehow find out the authserv-id(s) of our email server, so that
+/// we can use the Authentication-Results with the right authserv-id.
+///
+/// ## What this function does
+///
+/// When receiving an email, this function is called and updates the candidates for
+/// our server's authserv-id, i.e. what we think our server's authserv-id is.
+///
+/// Usually, every incoming email has Authentication-Results  with our server's
+/// authserv-id, so, the intersection of the existing authserv-ids and the incoming
+/// authserv-ids for our server's authserv-id is a good guess for our server's
+/// authserv-id. When this intersection is empty, we assume that the authserv-id has
+/// changed and start over with the new authserv-ids.
