Google may block sign in attempts from some email id’s that do not use modern security standards. It may show some error like, The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.

To fix this error change the account permission in gmail settings. After login to gmail click on this url: https://www.google.com/settings/security
