SMTP traffic monitoring

[David Lum]

We have Exchange 2007 here and I'd like to be able to see what machines are 
passing SMTP traffic  though it - how do I do that? it appears that it can 
create a CONNECTLOGnnnnn.LOG file - is there something that can parse it so I 
can view the connections easily?
