Contributing to the documentation

The documentation is written in RST, build with Sphinx and published by Read the Docs.

For the syntax, see RST/Sphinx Cheatsheet.

The shell.nix provides all the tooling required to build the documentation:

$ nix-shell
$ cd docs
$ make html
$ firefox ./_build/html/index.html


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


To test imap manually use

$ openssl s_client -host -port 143 -starttls imap
