  • Origami SMTP

    Origami SMTP was created with the idea to have a fake email server for testing purposes that supported TLS. This is because the code the developer was working on at the time had several hard coded values enforcing TLS so most other solutions would not work. Those that appeared they might work often crashed when dealing with TLS. Origami SMTP was born first focusing on getting enough of the SMTP protocol working to test it. After that STARTTLS (TLS) support was added.
