Run NixOS tests
---------------
You can run the testsuite via
::
$ nix-build tests -A extern.nixpkgs_20_03
$ nix-build tests -A intern.nixpkgs_unstable
...
Contributing to the documentation
---------------------------------
The documentation is written in RST, build with Sphinx and published
by `Read the Docs <https://readthedocs.org/>`_.
For the syntax, see `RST/Sphinx Cheatsheet
<https://sphinx-tutorial.readthedocs.io/cheatsheet/>`_.
The ``shell.nix`` provides all the tooling required to build the
documentation:
::
$ nix-shell
$ cd docs
$ make html
$ firefox ./_build/html/index.html
Nixops
------
You can test the setup via ``nixops``. After installation, do
::
$ nixops create nixops/single-server.nix nixops/vbox.nix -d mail
$ nixops deploy -d mail
$ nixops info -d mail
You can then test the server via e.g. \ ``telnet``. To log into it, use
::
$ nixops ssh -d mail mailserver
Imap
----
To test imap manually use
::
$ openssl s_client -host mail.example.com -port 143 -starttls imap
