You were misinformed.

The string expansion of %X, for various X, is not done for the logfile
directive of filters. It's only for the normal Exim logs.

You do have access to all of Exim's string expansion variables (except
for those explicitly prohibited in config); you should just be able to
use $tod_logfile instead of %D.
