What tools are available to generate bounce messages in order to test a bounce management tool? We want to test invalid addresses but we will like to test other error status codes.
A:
It sounds to me like you want an SMTP server that generates such errors in a reliable fashion.
Lots of open-source SMTP servers exist and are available for modification. One option is Apache James, a modular open-source Java SMTP server.
A much more trivial test server could simply open port 25 for receiving mails, and deliver canned errors depending on configuration (or incoming email).
