[exim] use one IP address but not the others

Hi,

I have one server wich has 2 network interfaces.
Exim sends mails wich appears to be from one IP, but I would like to
force Exim to send mails from the other one.

I dont care about the IPs it is listening on.

I'm running Exim 4.52, on Linux.

How could I do that?
Thank you.
