<bug_description>With banner-grabbing an attacker can see that this mail server supports ESMTP (Extended Simple Mail Transfer Protocol). ESMTP has additional vulnerabilities, so knowing that a network resource supports it permits an attacker to focus their efforts.</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. Do not allow the web server to include sensitive data (e.g. web server name and version) into the 404 Not Found report.</bug_solution>
