I create an e-mail account at unseen.is I have sent and received e-mail to and from that account, using Firefox browser and the e-mail service page. . I created / setup this e-mail using Thundebird. and it works ok BUT: I create a second e-mail account also at unseen.is, and that second account works ok [sent and receive e-mail to and from that account, WHEN using Firefox browser and the e-mail service page WEB. ] PROBLEM: I cannot create / setup the second e-mail using Thundebird. What I get is: user name or password invalid - AND configuration could not be verified - is the username or password wrong? as you can see at screenshot pic. I uploaded. thanks.
