this is a bug(?) in exim (i suppose you use exim3?)
file_directory = /var/spool/virtual/mail/${lookup mysql \
                  {USER_TO_USERID}{$value}{${local_part}}}
file = /var/spool/virtual/forward/${lookup mysql \
                  {USER_TO_USERID}{$value}{${local_part}}}.forward



the problem is, exim prepends the users homedir to relative pathes when
the save-command is used, but in your config is no real homedir/user,
BUT file_directory overrides this, and sets a homedir. This trick only
works with exim3, in exim4 you need some black magic to use relative
pathes in a virtualuser-enviroment.
