It's the POP3/SMTP addresses I need, setting up the account is the easy part

Looking at other forums there seems to be no SMTP settings that work for Hotmail or Yahoo without paying for a POP3 service!
mail.hotmail.com does not work, 'unable to connect to the server' error!
I just need someone with a Yahoo account to verify if they can upload files to their briefcase or attach files to e-mails when using an NTL connection!
