SMTPDummy v1.10

SMTPDummy is a "dummy" SMTP mail server that can be used by software developers for testing email sending software.
SMTPDummy is simple and practical, and responds to all SMTP commands in a positive manner (i.e. it accepts everything you throw at it), it does not however, store, forward or send emails. SMTPDummy does not require installation and is fully portable, you can run it from a USB stick. If does not require configuration, simply run the executable and you have a full (albeit dummy) SMTP server... :-)
Its purpose is to simply respond to SMTP commands without functioning as an SMTP server in any way. While it's running, you can see the server's log and the individual messages that it has received. Messages can be displayed as plain text or HTML.
You can use SMTPDummy for debugging your software sending application or for development and integration environments.
Finally, SMTPDummy can listen to any port number (defaults to 25).
