This is a small, scratch-based Docker image for running [nullmail
- A Null Router for SMTP][1], inside your docker-compose recipes, and beyond!
I was trying to deploy a docker-ized software stack, in staging / evaluation mode the other day, and ran across a fun behavior: it falls over and dies if it can't send email.
A while back, I ran into this in my travels in Cloud Foundry land, and I wrote [nullmail][1]. Now you can use it in Docker!
docker run -it -p 25 huntprod/nullmail
It doesn't actually do anything. The log stream (sent to stdout) can be useful at times.
