I've been checking my exim rejectlog and I've noticed the same IP address trying to do something on my mailserver. It looks like they aren't getting anywhere, but is there a way to respond back to their attempts on the server that would cause their process to just give up?
if you add the ip address to /etc/virtual/blacklist_domains you should be just fine. Since you mentioned you're using the nobaloney setup for exim.conf, I assume you're using DA, as I don't think he's setup that system for CPanel yet.

Thanks for the response. So do I just add the ip address in the blacklist_domains file or is there some syntax that I need to use? I just added the IP address in that file and restarted exim, but it doesn't seem to stop them. Still seeing them popup in my rejectlog.
