For some reason Thunderbird is issuing a "RETR 0" command which the server says is invalid.

I've tried setting up new profiles on the same machine, on new/freshly built machines (Win7) with no luck, no change.

This is account I've been using for years.

I have wireshark dumps of the POP3 session if that would help.
