Yahoo Incoming Mail Server (POP3) - pop.mail.yahoo.com (port 110)
Yahoo Outgoing Mail Server (SMTP) - smtp.mail.yahoo.com (port 25) (requires authentication, found in more settings where you enter server names, use same details as incoming server)
Account name- your full yahoo email address
password - you normal pasword you'd use to access webmail
That all seems to be correct but when the pop up box appears, everytime I click ok, it just keeps popping up continuously and nothing else happens! I have to cancel everytime but thanks for the tip!
