<bug_description>The remote host is running a SMTP mail relay. This one could be used to send emails. It may also be possible to specify wrong sender addresses - This could be used to send spam or junk mail.</bug_description>
<bug_solution>The server should be deactivated or de-installed if not necessary. Do not allow everyone to send emails over your mail relay. And do not allow arbitrary sender addresses to be specified. To make it harder to find the server the daemon could be configured to listen at another port (e.g. 8025). Try to prevent unwanted connection attempts by filtering traffic with firewalling. Alternation of the application banner can confuse an attacker and let him determine the wrong software.</bug_solution>
