What is MailSlurper?

MailSlurper is a small SMTP mail server that slurps mail into oblivion! MailSlurper is perfect for individual developers or small teams writing mail-enabled applications that wish to test email functionality without the risk or hassle of installing and configuring a full-blown email server. It's simple to use! Simply set up MailSlurper, configure your code and/or application server to send mail through the address where MailSlurper is running, and start sending emails! MailSlurper will capture those emails into a database for you to view at your leisure.

Get Started

Download

To begin first you must download the version of MailSlurper for your operating system. If you are on a Mac running OSX you will need to download the file named mailslurper-x.x-osx.zip. If you are going to run MailSlurper on Windows download the file named mailslurper-x.x-windows.zip.

Configuration

The next step is to extract the contents somewhere. It does not particularly matter where. Once extracted you will wish to review the configuration details in config.json. For this example let's say you are going to run MailSlurper on your local machine. There are three addresses and ports that need to be configured.

  1. Web application address and port

  2. Services address and port

  3. SMTP server address and port

Let's see what that might look like if we wanted to access the web-based administrator using http://localhost:8080, with services running on port 8888 and the SMTP server running on port 25.

Running Mailslurper

Now that you have MailSlurper configured all that is left to do is run it. Run the executable file named mailslurper for OSX, mailslurper.exe for Windows. Now open your favorite web browser and browse to http://localhost:8080. Congratulations! MailSlurper is now ready to slurp up mail for any of your applications and development projects set up to send mail to localhost on port 25!
