smtp

I'm getting a lot of messages like these:

me@home:/etc/snmp$ tail /var/log/syslog
Jun 12 17:52:15 home nullmailer[1238]: Starting delivery: protocol: smtp host: mail. file: 1339502401.24665

Jun 12 17:52:15 home nullmailer[1238]: Delivery complete, 331 message(s) remain.

The problem is, I don't recall sending anything. How do I find out which software is sending these messages? How do I read them?
