In commit 3f9d0c0762, we added a new possible private file. If the file
exists but there's an error reading it (common for permission issues),
currently we just move on to the next file, and if it doesn't exist we
may give up with that error.
That can "hide" the access problems making them harder to debug.
To help with those kinds of errors, this patch updates the logic to
return an error if a private key exists but is inaccessible.
It also adds an unit test for this function to cover the different
scenarios, and updates the docs to match.
The install guide mentions that the `certs/` directory can be symlinked,
but doesn't cover permissions much, so it's easy for users to be
confused (like it happened in
https://github.com/albertito/chasquid/issues/26).
This patch adds a bit more details on how to set up certificates, to
hopefully reduce the chances of confusion.
This patch updates and extends the links to the distribution packages,
referencing them from the README (it's more likely to be what the reader
wants to see), and also extending the Arch packaging with binary package
information.
There is an AUR package for chasquid, so this patch adds references to
it in the documentation.
Thanks to Max Mazurov (fox.cpp@disroot.org) for adding the package.
This patch updates the installation guide to try to make the
installation section more readable.
It also assumes a modern Go environment is installed, which
simplifies the process of building from source.
Rspamd (https://rspamd.com/) is a popular open-source spam filtering
system.
This patch adds integration with it in the example hook, which uses the
rspamc client to get a veredict, similar to what it does for
Spamassassin.
This patch adds configuration to integrate with readthedocs.org, using
mkdocs as rendering engine.
It also does minor documentation updates, to tidy some things up
(clearer titles, move some documentation from the root into docs/, etc).
