I have had my Yahoo account for some years now and have often had difficulty sending mail. I then took a yearly subscription in the hope that the difficulty will be resolved. Incoming mail is received, but sending mail is almost impossible. I contacted my internet service provider for assistance. He advised me to change one or two settings, but I still could not send mail. Now I don't know how the change the setting back and I can not find anywhere to mail Yahoo and ask for assistance.
Can anyone help please. I'm very frustrated because of this and have now opened a gmail address. Maybe the service there will be better.
