Assumpte: [exim] How to set sender?
Hi all,

I have recently implimented IP accounting software that indicates to me that
any outbound email is being sent via 1 specific ip address, this address is
the servers main domain ip address. Since I am monitoring users bandwidth, I
would like to ensure that any outgoing email is sent via thier domain and
accounted for using thier IP address.

Up until this point, I thought this was setup correctly, but I was mistaken.

Does anyone have any hints, or suggestions to help me 'make it happen'?

Details:

5 Physical Servers,
Each Server using its own installation of Exim,
Each servers has ~ 300 domains,
Each domain has its own IP address,
Each domain has a ability to host Virtual Pop accounts and valiases.
Mail User = mail
Mail Group - mailnull
OS = FreeBSD 4.10, 5.4 6.0 .

Router and Transport config shown below. I am not asking for anyone to spend
time reviewing my configure file, but if someone wants to and let me know
what they think of it, and if there are any big problems with it, here it is
...
