How to setup a fake SMTP server to catch all mails?
Solution 1:
If you have python lying around this will write the SMTP conversation to stdout.
sudo python -m smtpd -n -c DebuggingServer localhost:25

Solution 2:
You should have a look at smtp-sink which is a part of Postfix. You don't have to run Postfix to make it work. Just install it to have the executable. Everything you need can be configured via command line parameters:

Solution 3:
There is also a ruby gem called mailcatcher.
You can read the emails directly in your browser through the integrated web interface, there's a screenshot from their homepage below.
