I cannot send or receive e-mails under Firefox. the saved passwords under Options is blank. Under Get Messages I get the following: Sending of password for user [email protected] did not succeed. Mail server pop.att.yahoo.com responded: Server error - Please try again later. When I try to send messages I get:Enter your password for [email protected] on smtp.att.yahoo.com Also my phone keeps asking me to enter a new password. And when I go to mail.yahoo.com I get Invalid Password Please try again.
