    Just thought the group would like to know that Matt Madison sent me
a message that cured the problems I was talking about the last couple of 
days regarding problems with an "invalid address" of Postmaster@mynode...

    As usual, Matt was able to pin down the problem & offer an easy fix.
In case anyone else runs into this, here's my latest posting & his answer:

    and, as usual, he was exactly right! After adding the above command
via MCP, everything worked wonderfully!
