I've been playing around with this bug a little bit.  I understand what's
going on, but there is something I'm a bit confused about.  I get all the
right stuff in the qf* file and if I have sendmail process it by doing a
sendmail -q I see the expected behavior.  But when sendmail processes
the incomming messages immediately it ignores the extra R<whatever> line.
The stuff all shows up in the delivered message, but sendmail doesn't act
on it.

So what I'm confused about is this:  What is different about the way
sendmail processes the queue files when it is called with the -q option
and when it is just processing off smtp connections?  I see the exact same
behavior on 8.6.9 running on 4.1.3 and Linux.
