[exim] Logging more information

Hi,

(Using Exim 4.67) Under certain spam fighting circumstances mail is
delayed. Much of that mail disconnects and Exim logs "unexpected
disconnection from <host> <IP address>". Unfortunately, the host and IP
address isn't really enough to tell me anything meaningful, like whether
or not the mail was a ham. I need to know if it was a ham. Is there a
way to make Exim tell me more information, like $sender_address_domain,
should the disconnect occur during the Rcpt acl (which is where the
majority of these disconnects occur)?

Thanks!
Craig
