A (work in progress!) simple Python implementation of an SMTP server, leaning heavily on protocol defined in RFC 5321.
Install the given requirements: pip install -r requirements.txt
Rename sample.env to .env, and reconfigure as desired.
Open two separate terminals. In both, navigate to the src directory.
- In the first, launch the server:
python server.py - In the second, launch the client:
python client.py
Note that the client is only for demonstration purposes. It's a very naive implementation and relies on user input for everything.
By default, the server will run on localhost:2525 (normally mailservers would
run on port 25, but that requires privileged access).
