netstat -i

Honestly, if you're running a firewall through which all this traffic
is passing, it should be keeping logs of all this activity.  If it 
isn't, then most here would suggest you consider a different firewall.

That doesn't necessarily mean that this info is being summarized, but 
a decent shell or perl script could be written to parse it out any 
way you'd like.

If, instead, this traffic isn't going via a single machine, you're
only going to be able to get specific information on a machine-by-machine
basis, assuming such logs are kept.  Sendmail can be configured to log
everything to the syslog, but I don't think the sgi version did by default.
(I compiled the real one so fast I never had a chance to see.)

If the latter is the case, most likely your router can give you some 
overall information broken down by protocol (show interface on a Cisco)
but might not give you a per-machine breakdown.
