[Nottingham] Disable Ports

[Peter Chang]

Johan,

You need to examine the headers of the spam alleged to have come from your
server and check the logs on your server.

Web servers are vulnerable to many attacks - you need to read up on these
and how to secure your server. Mail servers can be badly configured to
allow spammers to relay their emails. Ssh access should be restricted to
(trusted) named users (no root) and ideally not use password
authentication.

Use google to find resources. You shouldn't need to bombard this list with
requests for help for your (commercial?) net enterprises: your users are
relying on you not this LUG.

Peter
