Protocol and bandwidth analyzer

With all the spam coming into our mail server, I was curious to find
out how much bandwidth it is using. Our network services provider
hooked into the Cisco switch and monitored the port where the internet
router is connected. He used Network Instruments Observer Suite - It
was pretty nice. We could see all traffic by IP address, host name,
protocol type, etc. I like this as a troubleshooting tool, but I am
sure I don't need all the functionality of the Observer suite.
Any recommedations for a tool that will allow me to monitor all
traffic on a port and break it down like I mentioned above? I would
also like to be able to monitor more than one port on the switch at a
time. Cheaper is better! Thanks.
