Stopping sendmail auto generated messages

Every time i try to start sendmail roots mailboxes immediately fill up with hundreds of copies of the below message. I have checked and i dont have a program called "hddtemp" on my system. The bolding in the below is mine. Im posting this in the slackware forum because it must be some sort of system config problem. I have never seen anything like this before, anyone know what program is sending these emails?

Code:

It says it is system configuration error. As a matter of fact, it is system configuration error.

no kidding. I meant that it is not JUST a sendmail config error, its a system config error that something is trying to send the email at all.
I started sendmail to begin configuring it but that is impossible while something is using it to send spam. Im looking for help on figuring out what that something is.

Thanks for the tip. I checked the cron spools and the atd config and couldnt find anything.
It is fixed and im not sure what fixed it.
What i did was log out all the users and started killing processes in runlevel 3 and starting and stopping sendmail to test.
When i killed the udevd daemon the problem disappeared. I cleared the clientmqueue and mqueue directories and rebooted and the problem has yet to reappear. I still dont know what happened or how i fixed it really. My only theory is that when i was playing with lm-sensors a couple of days ago something got stored somewhere that was sending this mail.
Thing is the mail was dated to the time i started sendmail to test it.
If anyone has another theory id love to hear it.
