Philip and I passed around long and verbose debug messages off the list and finally found the problem...just for the list's sake and archive's sake, I figured I'd post the solution.
After running strace on the child exim process that actually processes the message, we saw there were attempts to access /var/tmp which had the incorrect permissions (no write permission). This is probably a DB thing, so naturally Exim wouldn't report these errors. Fixed the error by making /var/tmp world writable like a temp dir should be.
And all this time I thought it was in a totally different directory...wild goose chase? strace can be your friend :)
