I took your suggestion of rebuilding the transport file and rebuilt that as well as the relay_domains and relay_recipients files.
I ALSO deleted the .db files to be sure they were recreated. Perhaps you meant for me to do that in the first place, but I did not the first time around.
I am not sure why, but this FIXED IT !!! Mail is now flowing all the way through and looks like everything is working properly.
Thanks Again... Do you know why this worked? Since you suggested it, I suppose you have seen it before? Any insight as to what is happening there?
