I am having trouble emailing photos from iphoto through Yahoo. I get all the way to Send, then I am told my Yahoo password is invalid. Dead end. What am I doing wrong?
Is Mail working to send mail normally, or are you usually using another app to send mail the rest of the time? iPhoto just hands photos off to Mail, so usually if you can send regular email, you can send a photo.
Last I heard, you needed a paid account (depending on global region) to set up a Yahoo POP account in Mail, has this changed? If you don't have a paid account you may not be able to authenticate with their outgoing mail server properly.
