[exim] Logging of outgoing IP

Dear Team,

I want to log outgoing interface IP Address in exim log file. I goggled on web but found nothing.

In my exim setup, I am using multiple (Random) IPs to send mails, But I want to check which mail send by which IP Address OR how many mails send by each IP Address..

Is there any way to log outgoing IP to exim log file ?

Thanks & Regards,
