If I was to post the whole log -- There at least 30 of these warnings:

Funny thing is I just got this ISPConfig running 2 days ago, and have only sent out a couple testers to see if my contact forms are working.
Sad if someone hacked in already, before I have had a chance to figure ISPConfig out.
Either get rid of it --Or -- I just wait for the SPAM Police to come and take me away ... lol
