I want to send mail from Outlook Express from now on and i have an problem.I can't send any messages from Outlook because of some error.I cannot send because i can't log on to server "smtp.mail.yahoo.com". I enter my user name and password and i click OK.After a few seconds i get the same log on screen,and it can't stop.I know my login and password so i don't know why is this repeating like it is not correct.
