Build your own disposable email server like mailinator

originally posted on https://blog.jutsu.mx

The goal is to have a disposable server for disposable email.

This can be easily done with docker and inbucket

TL;DR

docker run -it — rm — name inbucket -p 9000:9000 -p 25:2500 -p 1100:1100 inbucket/inbucket

Prepare your DNS record

In your domain registrar, go to DNS management and add an entry in case you don’t have one. You can use whatever you want.

In this example, I want to send any emails to `test.softwareinarush.com as in `2308uasdfA@test.softwareinarush.com`

Add an A record that points to your server

On the server, spin up a new container

Simply run:

docker run -it — rm — name inbucket -p 9000:9000 -p 25:2500 -p 1100:1100 inbucket/inbucket

This will start a temporary container with all you need:

* Web UI 9000 to see emails in real time.
* Open port 25to receive email (_could be changed but this works even with the `mail` command in MacOS_)
* Optionally use port 1100 for POP3 (I don’t)


#### Test it
Send a test email from command line (or other email service)

mail -s “test emai hashmail” ninjutsu756@test.softwareinarush.com <<< ‘This is a message’

Email should be visible in the `Monitor` page


Once you’re done, you can `Ctrl + C` to terminate the container.
