[Exim] pam & rhost question

Hi!
I'm using exim with pam authentication, with my own pam module, which logs
remote host ips of a connection if it's available. But exims pam
authenticator doesn't export that variable, so I'm unable to log it.
Is there an easy way to solve this problem, or this may be a feature request?
Thanks!
