I appreciate your describing this in detail. I'm going to need some time to
reflect on these assumptions.

I know the qmail documentation says that the default for qmail is not to
relay. I need to see proof, not just be told to assume that the
documentation is correct. As I said above, I'll need time to reflect on
this. I appreciate that someone else suggested asking ORBS to do a relay
test. However, that doesn't necessarily reassure me that the Prodygy
Solutions relay test results should be ignored. I don't know anything
specific about the Prodygy relay test "failures" but I don't just ignore
something because someone else said to.
I do appreciate your reply and I realize full well that I may end up
deciding to ignore the Prodygy relay test failures someday myself.
