<bug_description>An attacker who is able to get a direct connection to the port can identify the banner of this mail server as Sendmail. By this knowledge further enumerations and attacks are possible.</bug_description>
<bug_solution>A service if not needed should be de-installed or disabled. If this is not possible, an access control list (ACL) with firewalling should be applied to this port. Change the application banner to confuse attackers.</bug_solution>
