Cisco PIX Firewall Mailguard Feature SMTP Content Filter Bypass

This script is Copyright (C) 2000-2012 Tenable Network Security, Inc.

Synopsis :

The remote service is vulnerable to an access control breach.

Description :

The remote SMTP server seems to be protected by a content
filtering firewall probably Cisco's PIX.

However, an attacker may bypass this content filtering
by issuing a DATA command before a MAIL command,
that allows him to directly communicate with the real SMTP daemon.
