Description

This module exploits a command injection vulnerability against Dovecot with
Exim using the "use_shell" option. It uses the sender's address to inject arbitrary
commands, since this is one of the user-controlled variables. It has been
successfully tested on Debian Squeeze using the default Exim4 with the dovecot-common
packages.
