Gmail won't allow your application to send email anonymously due to security reasons. You must turn ON the less secure app to send email https://www.google.com/settings/security/lesssecureapps

open "[email protected]", you must have got a mail with subject Review blocked sign-in attempt

you will find a link " allowing access to less secure apps" at end of mail.

click it and set Allow less secure apps to ON
