Super simple mailsink with Python

If your script or app sends  mail and you’ve got no time or don’t feel like configuring a real SMTP server, use a mailsink. A debugging method that in it’s simplest form just displays the result of the SMTP conversation, namely the message.

Fire up a terminal an run this code:

python -m smtpd -n -c DebuggingServer localhost:3000

This listens on port 3000 on your localhost ( If you need port 25 (the SMTP default port), just run the line with sudo and enter your password:

sudo python -m smtpd -n -c DebuggingServer localhost:25

That’s it. Enjoy.
