One on my accounts started giving me errors when I try to open emails. "Invalid UID Fetch attribute XSENDER" I only get this with this account. This account does this on my 2 machines with Thunderbird. Installed Thunderbird on a 3rd PC (with no plug-ins) and same thing. E-mails downloads, I can send, but I get this message when I try to open emails.

Installed eM Client to test the account, everything is fine in eM Client. I can also work from the ISP webmail interface with no problem.

It's only this account in Thunderbird. !?
