rcx / email-parser

A handy webapp to render raw email data.

Online email parser

A companion project for tcpbin.

This is a simple Flask webapp that just parses raw email data and renders a webpage to display it. Although it doesn't strip dangerous tags like <script> or <img>, these are mitigated by enforcing an extremely strict Content Security Policy (default-src 'none').

Try it online

https://tcpb.in:5000

Setup

git clone https://github.com/ecx86/email-parser
cd email-parser
sudo pip3 install -r requirements.txt
export FLASK_APP=app.py
python3 -m flask run

Note that it's better to run it under wsgi if you're hosting it permanently.
