SMTP Dummy is an SMTP mail server specially designed for software and web application developers, so they can perform their email sending tests.
Its operation is very simple and practical, and incorporates an intuitive interface so you can operate with SMTP Dummy without problems. It responds to all SMTP commands in a positive way, but cannot be used as a mail server itself, as it works only as a test. Use SMTP Dummy to check if the program you created works correctly, and debug your sending errors. It can work through any open port on the router, but by default it will take port 25.
To adapt it to your liking, SMTP Dummy gives you the option to modify the background color and text of your command console.
You can free download SMTP Dummy 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
