In MySQL you have to authorized a user based on the name of the origin network. From my network to a remote one all connections appear as sent from mail.mycompany.com. But connections to another remote network it appears with a different origin. How to discover which name/ip it is using?

I tried tcpdump and netstat in the destination but it is difficult to find my connection among billions of others.

In my case the destination is a Windows Server 2003
