Running Mavericks and Apple Mail. Have AOL and Verizon e-mails configured on Apple Mail; using Verizon/Yahoo for Verizon.net mail. When sending an e-mail, I'm prompted for the password once or twice before it is sent. This only occurs with Verizon e-mail, and not AOL. It also does not occur on my IPhone. I think this issue has been brought up before, but I'm having a hard time finding an aswer. I've run KeyChain First Aid by the way.
