Sorry I wasn't clear enough.  The order is a bit wrong.

For locally generated mail, the submission agent firs tries to send the
mail to the local daemon through SMTP.  If it succeeds, the mail will go
to mqueue.in.  If it fails for a temporary error (e.g. DNS timeout in
trying to canonicalize sender/recipient domain), the mail will be put in
clientmqueue.  The clientmqueue queue runner will pickup the mail later
and deliver it to the local daemon.  So the mail will end up in
mqueue.in anyway.
