Great Results with SpamBlocker2 and Mod_Security on the Server Level
If your site is hosted on our DirectAdmin server you will notice that the junk mail sent to your domain’s inbox get reduced by 90% or more. Why? Because we have installed SpamBlocker2 on the server level which identifies existing email spam signatures according to several common blocklists as listed here:

BTW, that is where a legitimate email sender will be sent to when his or her email address is falsely identified. This way a legitimate user can send us a request to unblock the falsely identified email address - this may mean we add that email address into our whitelists or remove it from our blacklists.
Note that we achieve about 90% spam reduction without blacklisting any email or email domain on our local server - we are simply using those popular third-party blocklists.
To further tighten up our DirectAdmin server, we have installed mod_security which monitor HTTP traffic in real time to identify malicious activities.
With these measures employed, CPU usage by malicious activities can be cut down to the minimum so that your website loads much faster than before.
