Right. So that won't catch messages submitted via SMTP from your local
(windows) clients. I presume that's ok? If you're not sure about where
qmail-inject and friends fit into the scheme of things, carefully read
and understand all of the PIC.* files in the qmail source before
proceeding.
I also assume you're aware of the MIME related issues in trying to do
this. It's been discussed many times on this list - the archives are
your friend.

Well, qmail-inject doesn't log particularly. It's meant to be invoked
from a shell and thus informs you of results via stderr and the exit
code.

multilog is *nothing* like syslog. You just can't make a call to write
to stderr in one process such as qmail-inject and magically have it
show up with the output of some other process such as qmail-send.

You might want to actually copy the way qmail-inject generates its
messages. Hint: search for the string "memory".
