For whatever reason, I had five different CNN email adds bounce back to me yesterday, and another one just now bounced back in Firefox. Todays bounce back or failure, is shown in the image I attached below. I'm not an IT PROFESSIONAL, and since errors like this happen so RARELY, i don't understand just what the reason is, for all these email attempts, failing to be delivered. If I knew what was causing it, maybe some setting that needed changing, or something has been corrupted, I could reinstall, that would help me solve this. But, I can't understand what all this is trying to tell me. Does anyone understand this, and can help explain it to me? Thank you.
