how could this be exploited?
An open SMTP relay is running on this port.
The remote SMTP server is insufficiently protected against relaying.
This means that it allows spammers to use your mail server to send
their mails to the world, thus wasting your network bandwidth.
Reconfigure your SMTP server so that it cannot be used as a relay
