Gotcha.  I guess someone thought it was a true bounce and configured their servers appropriately. :^)

I will certainly be encouraging people with RR addresses to switch.  

I have not yet tried the nuclear option - the infamous EECB (Executive Email Carpet Bomb).  This of course should only be used when all other options have been exhausted.  I’ll probably end up doing it with the Time Warner people.  I did it a few years ago when I was (having no success) going through the usual channels of AOL marking mailing list email as spam.  Within 2 hours of the EECB I got a call from one of their Anti-Spam Operations team members, and she gave me her direct phone number and email address at that point for any future needed correspondence.  Things started happening then.
