It's a subsequent error - your authentication failed, hence you're not permitted to send anything either. Authentication credentials (account and password) and method (plain or other) must all be the right ones. Check which you're using in your e-mail client where you're hopefully able to send e-mails.Andrew Clarkson wrote:
