You start up the secondary copy of sendmail in deferred mode.  This means 
that *EVERYTHING* hits the queue first-thing, and no delivery attempt is 
made until the queue runner gets to it.

That's the point of deferred mode.  If you don't want that, the you need to 
start up in something other than deferred mode.
