Open Account Settings, Outgoing Server (SMTP), bottom of left pane. If the port is 587, the connection security is generally STARTTLS and the authentication method is 'normal password'. If the required security setting is 'none', the authentication should be 'password, transmitted insecurely'. Otherwise, contact your webhost for precise instructions.
