    We have exim running on a server and got a notice that a client is sending spam. Unfortunately the mail is not going through exim as far as I can tell and there's nothing in the logs about it as a result.

    How can we prevent other scripts that are running perhaps (couldn't find it in the process list currently but maybe they were before) from using outbound port 25? I only want exim to be able to use it.

    Instal CSF - it already has an option to limit using 25 port to cpanel/sendmail/exim.
