Build your own disposable email server like mailinator

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 25 to 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.
