On my primary PC with Windows 7-64bit, I have my server settings to leave messages on the server for 55 days. I need to download the old messages again into Thunderbird probably due to some problems with Time Warner Road Runner sometimes blacklisting Netflix e-mail (if that is the proper term). Netflix is aware of the problem with TWC bouncing their e-mail. I know that if I went to another PC with Thunderbird--all the old and current messages from the last 55 days should be downloaded to it. But how do I download them again (if possible) to my primary computer with Thunderbird? If I go to web based e-mail at TWC, my old messages from up to 55 days are listed.
