MailEnable SMTP Connector Service SPF Record Crafted Lookup DoS

This script is Copyright (C) 2006-2014 Tenable Network Security, Inc.


Synopsis :

The remote SMTP server is affected by a denial of service flaw.

Description :

The remote host is running MailEnable, a commercial mail server for
Windows.

The SMTP server bundled with the version of MailEnable installed on
the remote host reportedly suffers from a flaw in which SPF lookups
for domains with large records may result in a NULL pointer exception
in the SMTP service. An unauthenticated, remote attacker may be able
to exploit this issue to crash the affected service.
