You'll have to use Netflow or SNMP for that.

Collin Thanks.

ASA 8.0 dont support netflow.

With SNMP I can get in/out bandwidth using tools (SolarWinds), not clear how to get SMTP traffic using SNMP.

Sorry, I was thinking just the interface, not a specific protocol. The only way that comes to mind is to check syslog. It shows the number of bytes during a TCP connection. Then you'll have to add them all up. Linux could be a great help here if that's an option. Some shell scripts could automate all that for you. There probably are some commercial products that do it, but I don't know of any.
