Test Mail Server Tool is a full featured mail (SMTP) server emulation to test mail sending capabilities of a web or desktop application or to preview messages before they are actually sent. This is a great tool for web programmers or application developers who need mail server for tests but don't want to install one.
The program listens on localhost on a SMTP port (usually 25, may be changed). All mail sent to this tool is automatically stored and optionally opened with your mail client.
Points of interest:
Other benefits are streamlined install, ease of use, small size, and easy uninstall. One of the important things is that this edition of Test Mail Server Tool is free.
