Logging of FQDN in exim's logs

Sorry if this is an old one...

We're running 1.61 on solaris 2.5.1 on some machines. Some of our users
are used to mailing user@site (where site != FQDN). Exim accepts this
and sends if it can expand the address. Is it possible to get exim
to log the expanded address? Logging the remote mta is fine but if it
has access to the domain (which it should have??) can this be logged as
well?

Thank you
