I was using WebMail add-on since >1 year without a problem with Yahoo, but it stopped working since 30 March 2011, Thunderbird is returning "Alert": Sending of password did not succeed. Mail server localhost responded: negative vibes from xxx@yyyy"
Yahoo provides POP access just for PLUS (paid) clients, I just tried IMAP like Hartley Nemerov, >The regular IMAP mode is working for me with the free accounts or at least >it is working here for now. I not able access the pop3 anyway on the >business system due to firewall setup. > >If my memory is correct it is posted at the Yahoo Site that pop3 is only >available to paid users. it works without a problem, I'm able send and receive e-mails using Thunderbird 3.1.9. -Mark
