+    <p>A remote attacker, by connecting to the SMTP listener daemon, could
+      possibly execute arbitrary code with the privileges of the process or
+      cause a Denial of Service condition. Furthermore, a local attacker could
+      perform symlink attacks to overwrite arbitrary files with the privileges
+      of the user running the application or escalate privileges.
+    </p>
