/usr/sbin/exim -bd -q60m

That actually is starting a Exim daemon. You won't be able to receive emails until you start that.

The -bd option causes the daemon to listen for incoming SMTP calls, and the -q60m option causes it to start a queue runner process every 60 minutes.

How come there are more than one of that process running?
