Thunderbird will not download most of the messages in my email queue.

When I ask Thunderbird to "get messages," I get a response that says there's an error with the [email protected] account, followed by this message: "The RETR command did not succeed. Error retrieving a message. Mail server pop3.frontier.com responded: [SYS/TEMP] problem retrieving message." I checked with frontier.com and they insisted the problem wasn't at their end, which I believe because the messages do download in Outlook onthe same computer (with Windows 10) and on my iPhone. There's a second account on Thunderbird and it works fine. And, periodically, one or two dozen earlier messages on the dkharvey account will download out of the blue, but at last count there were still 1,295 messages backed up somewhere.

Matt:

   Two questions:
   1. Do I only copy the mail and news account info?
   2. What is "your post" that I paste it into?

Thanks
