OK, um, using this, and yahoo express...
I go to logon, I type in my password I hit OK. This is all after I have set all of this stuff up and it supposedly should work.
I hit OK, the little login screen goes away for like 1 nano second, then comes back on, so i hit cancel. So I go to that little window and go to the errors.
There was a problem logging onto your mail server. Your Password was rejected. Account: 'pop.mail.yahoo.com', Server: 'pop.mail.yahoo.com', Protocol: POP3, Server Response: '-ERR invalid user/password', Port: 995, Secure(SSL): Yes, Server Error: 0x800CCC90, Error Number: 0x00CCC92
and my password is correct! I am putting in the right password! Don't say I am not, because i am, the one i use here works on mail.yahoo.com the website. so like wtf!
I also have thunderbird installed and all the same settings in it. I put in my password for that and it says, Sending of password did not succeed. Mail server pop.mail.yahoo.com responded: invalid password.
I'll give you rep if you can get this to work!
