Ok, I did more searching and came up with this page, which led me to look in my process list.

So, I found a couple of sendmail processes that had high times, one of which had the process id 10216, so I terminated them both. We'll see if I continue to get that error type in my logs.
FYI: I'm still somewhat new to Linux, so trying to learn.
