... as long as your Apache user or group is listed in trusted_users or
trusted_groups.

Assuming that your CGI is doing a fork/exec of exim, another solution is
temporarily to replace exim with a script which makes a note of what its
parent is, which at that instant should be the CGI itself. This means you
don't have to touch the scripts themselves.

Example (untested): if you are invoking /usr/exim/bin/exim, move it out of
the way and replace it with

#!/bin/sh
echo "I am $$, parent is $PPID: `ps -p $PPID`" >>/tmp/exim.log
exec /usr/exim/bin/exim-4.50-1 "$@"

Remember to chmod +x this script. Any lost mail as a result of experimenting
with this script is entirely your own responsibility however! :-)
