Dummy SMTP servers for testing

As part of testing apps that send email, we needed some way of sending emails to a server and seeing what was sent and that it actually *was* sent.


However, we did not want to flood a real SMTP server with hundreds or thousands of emails.


The following 2 tools assist with that problem:

• DevNull SMTP server
  Described as

  It is a dummy SMTP server that can be used for testing purposes. It helps you see all communication between a client and the server and is very useful if you are trying to find problems with your email server or a client that you wrote.

  
  
• Dumpster SMTP server
  Described as

  The Dumbster is a very simple fake SMTP server designed for unit and system testing applications that send email messages. It responds to all standard SMTP commands but does not deliver messages to the user. The messages are stored within the Dumbster for later extraction and verification.
