The Simple SMTP Desktop Email Receiver
Ever need to test emails from an application or web site but don't want them accidently being sent or having to deal with the hassle of setting up a test email server? Papercut is a quick email viewer with a built-in SMTP server designed to only receive messages. It doesn't enforce any restrictions how you send your email. It allows you to view the whole email-chilada: body, html, headers, attachment down to the naughty raw bits. It can be set to run on startup and sits quietly minimized in the tray giving you a balloon popup when a new message arrives.
The dotnet core based version of Papercut is a cross platform, Docker images are also available.
The .netcore based applications are not released yet. You can download the released versions or try the nightly builds at this time.
You can also use Papercut directly with Docker:
docker run --name=papercut -p 25:25 -p 37408:37408 jijiechen/papercut:latest
In development mode, the Papercut.Service will defaultly listen SMTP service on port 2525. You can use the send-test-mail.js in the root directory to test Papercut.Service.
npm install nodemailer
node ./send-test-mail.js
For the desktop app, you run it by executing the start-electron-app script in the src/Papercut.Desktop directory:
cd src/Papercut.Desktop
./start-electron.sh # on Windows, use .\start-electron.bat
To attach and debug the Electron app, just launch the development tool and debug the web page in electron.
If you'd like to debug the backend Papercut when running in electron desktop mode, add a DEBUG_PAPAERCUT environment variable and give it a value before launching the desktop app, the program will wait 30s for the debugger to attach.
