[exim] Maildir filename in Exim log

Hi!

Is it possible to log the name of the file used to write an mail in Maildir
folder?

Exim write to log it's ID for an incoming mail, but I need to have a direct
conection between this Exim ID and the name of the file wroten in Maildir
folder (the time.pid.host filename).

Thanks!

Israel.
