I use Mac mail, and frequently get a request for my password when sending an email. When I enter the password, it says the account already exists. I click cancel, and then the email sits in my outbox (and if I open it again and click send, it goes no problem). What is happening here and how do I get it to stop?
Mac mail may require a more secure password. I'd recommend updating your password to something very secure through your MyShaw account, then updating your Mac mail settings with the new secure password.
