Did you tried Simple Java program to send the mail? http://www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/ — Subodh Joshi, Aug 14 '15 at 06:19
in your actual code do you replace `sender` & `receiver` with actual mail id or not? — Bond - Java Bond, Aug 14 '15 at 06:20

We had into the same problem sometime back, with Spring Boot 1.2.5. Looks like with the latest version of Java Mail, now another property is needed - spring.mail.properties.mail.smtp.ssl.enable to be set as true. See this post for details.

Also, when I tested my application, I saw that merely giving the regular gmail password didn't anymore work. I needed a 2-step verified account, and had to use an application password.
