Right on both counts.

The files under queue/pid are empty. qmail-queue moves them to
queue/mess before writing the message to the file. This is all
documented in INTERNALS in the build directory:
3. How messages enter the queue
To add a message to the queue, qmail-queue first creates a file in a
separate directory, pid/, with a unique name. The filesystem assigns
that file a unique inode number. qmail-queue looks at that number, say
457. By the guarantee above, message 457 must be in state S1.
qmail-queue renames pid/whatever as mess/457, moving to S2. It writes
the message to mess/457. It then creates intd/457, moving to S3, and
writes the envelope information to intd/457.
Finally qmail-queue creates a new link, todo/457, for intd/457, moving
to S4. At that instant the message has been successfully queued, and
qmail-queue leaves it for further handling by qmail-send.
qmail-queue starts a 24-hour timer before touching any files, and
commits suicide if the timer expires.
