Have setup Hotmail account and can receive emails but when trying to send I get error message: An error occurred while sending mail. The mail server responded: 5.7.0 Must issue a STARTTLS command first. Please verify that your email address is correct in your Mail preferences and try again. How and where do I enter this command line?
