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.
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.
{
"wwwAddress": "127.0.0.1",
"wwwPort": 8080,
"serviceAddress": "127.0.0.1",
"servicePort": 8888,
"smtpAddress": "127.0.0.1",
"smtpPort": 25,
"dbEngine": "SQLite",
"dbHost": "",
"dbPort": 0,
"dbDatabase": "./mailslurper.db",
"dbUserName": "",
"dbPassword": "",
"maxWorkers": 1000,
"keyFile": "",
"certFile": "",
"adminKeyFile": "",
"adminCertFile": "",
"authenticationScheme": "",
"authSecret": "",
"authSalt": "",
"authTimeoutInMinutes": 120,
"credentials": {}
}
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 setup to send mail to localhost on port 25!

I'm a software developer and entrepreneur. I enjoy writing software and mobile apps, and I dabble in videography and filmmaking. I built MailSlurper because I needed a tool to easily test mail functionality in applications without having to setup a real mail server, or worry about emails going out to real users by accident. I hope you enjoy!
