I recently installed RH9, my first linux install and have been making progress. When looking through the system log at sendmail I encountered sent/received messages that didn't quite look right to me, beginning here at Oct27 10:40:39--the h9RFedJC003568 mssg.

I haven't used mail on the system nor opened the email program. The logs for the previous two days that the system had been installed show nothing like this. Does someone know what this may be?
