[Disclaimer: I wrote the original maildir stuff, but thats many many
years ago, and things have changed substantially since then and probably
been rewritten a few times]
The maildir file name will be computed by the Exim final delivery
process[1]. This will normally run as a subprocess of the main process
because it will run as a different user ID to the main process (Exim was
changed around version 4.0 to never use seteuid but always use setuid
which is a non-reversable process, so having changed UID it cannot
regain its old privaleges). The logging will therefore be done by the
parent process, which will not have easy access to the information about
the final maildir file name.
So this may well be tricker than it at first appears.

[1] This is required because if there is a file name collision you need
to generate a new file name, so you cannot generate a filename until you
are at a point where you can try writing to this file.
