A Mock SMTP server for rails developers

For my current Ruby on Rails project I am using email based authentication plug-in clearance.

After the registration users get an email with an activation link, but at development environment I don’t have fully functional mail server. I don’t need it either. I just want to catch the generated emails and I don’t want to change my code to do that.

After doing some Internet search I found exactly what I needed.  Mailtrap a mock STMP sever. It is distributed as a gem.  You can install it with following command.

sudo gem install -y mailtrap

Let’s stat the mailtrap

mailtrap start

Since we didn’t specify any host or port information it will start default parameters.  (default: localhost) and port (default: 2525) for the server and also where the messages get written (default: /var/tmp/mailtrap.log)

You can get more information you can visit the documentation page.
