Chris,
Thank you for your reply.
There may be a fix pending for this issue, but the latest word I received from Cox Tier 2 Tech Support earlier this week (February 6) is that there is no firm (or even estimated) date as to when that fix will be implemented. In fact, I got the impression that resolution may be months away. That's why I'm desirous of having the retrieval problem escalated for immediate resolution.
Regarding my specific situation, there is one inbox message at the server (as mentioned in my original post) which apparently is causing the Error 127.0.0.1 problem I'm encountering. It's the first (oldest) message in my inbox--and is blocking all the others from being downloaded. Is there any way Cox can remove this particular message at the server? I assume once it's gone, I'll be able to download to my email client as normal.
I'll be looking forward to a positive response.
