Important

Current version of this code has moved into a proper GitHub repository: https://github.com/palant/opensmtpd-filters

The OpenSMTPD documentation currently suggests using either opensmtpd-filter-dkimsign or opensmtpd-filter-rspamd for DKIM support. The former lacks functionality and requires you to compile code from some Austrian web server yourself. The latter is overdimensioned for my needs. So I’ve written my own fairly simple filters in Python.

Prerequisites

These filters require Python 3 with dkimpy module installed. You can optionally install pyspf module as well, if you want dkimverify.py to perform SPF verification as well.

Setting up

Compile with:

webpack --config vendor.webpack.config.js
webpack --config app.webpack.config.js

Use with the following index.html

ABOUT

about:config settings to harden the Firefox browser. Privacy and performance enhancements.
To change these settings type 'about:config' in the url bar. Then search the setting you would like to change and modify the value. Some settings may break certain websites from functioning and rendering normally. Some settings may also make firefox unstable. I am not liable for any damages/loss of data.

Not all these changes are necessary and will be dependent upon your usage and hardware. Do some research on settings if you don't understand what they do. These settings are best combined with your standard privacy extensions (~~HTTPS Everywhere~~ No longer required: Enable HTTPS-Only Mode, NoScript/Request Policy, uBlock origin, agent spoofing, ~~Privacy Badger~~ etc), and all plugins set to "Ask To Activate".
