Cannot log in from Yahoo.com
My account was moved to Yahoo.com some time ago. Since then I have not been able to use Thunderbird. I get an error message "Sending of password for the user Sigma54... did not succeed. Mail server pop.mail.yahoo.com responded [SYS/TEMP] Server error. Please try again later". I have rechecked all my information several times. Seems to be accurate. I hate Yahoo and all their ads. Please help.
