Cannot send email with Mail program on iMac. Help!!!
I cant send emails with Mail program on iMac. This happened after the latest software update. I keep getting "enter password for account" but never had to before. Also the password I use when entered does not work. I don't know how to fix this, also my list of servers got screwed up because my wife and son tried to "fix" the problem. Can anyone help with a clear, step by step procedure to fix this issue?
