Question

I\'m in the process of testing an application that takes mail out of a mailbox, performs some action based on the content of that mail, and then sends a response mail depend

Answer 1

There is also very simple in use GreenMail which was designer as a mail server for automatic "unit" tests.

From projects web page (probably there are some others tools with sending/receiving functionality nowadays):

GreenMail is an open source, intuitive and easy-to-use test suite of email servers for testing purposes. Supports SMTP, POP3, IMAP with SSL socket support. GreenMail also provides a JBoss GreenMail Service. GreenMail is the fist and only library that offers a test framework for both receiving and retrieving emails from Java.
