[ExI] Help! - Fwd: Mail delivery failed: returning message to sender

[Stuart LaForge]

Any clue as to why about every other email I try to post to the list  
gets returned to me saying that my "PTR is likely forged". What does  
that even mean? How do I fix this? Should I switch back to my old  
Yahoo account?

Thanks,
Stuart LaForge
