I encountered similar delays just before VERP was enabled for
sourceware.org.  Apparently it was not possible to figure out the cause
of the mail delays based on the available Postfix logs.  As I result, I
don't know if it was Red Hat's email infrastructure or sourceware that
caused the delay.  Like in your case, the Received: lines only showed
that the hand-off between the two domains did not happen in a timely
fashion.

Thanks,
Florian
