Why I wrote this addon?
While researching email security for a few months I realized that there was a lot of nuance in how different email security protocols worked. It was very confusing at times and I wanted to organize all the different edge cases into a single tool that could help others identify these misconfigurations without having to read through dozens of RFCs. This extension was supposed to be 100 lines of code written in an afternoon, instead it has reached almost 2,000 lines of code over multiple months.
