I'm trying to send an email using Spring Boot. However, I get the error below in the console. I try the whole thing with GMX as email provider

Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed: org.springframework.mail.MailSendException: Mail server connection failed. Failed messages: javax.mail.MessagingException: Could not convert socket to TLS; nested exception is: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate); message exceptions (1) are: Failed message 1: javax.mail.MessagingException: Could not convert socket to TLS; nested exception is: javax.net.ssl.SSLHandshakeException: No appropriate protocol (protocol is disabled or cipher suites are inappropriate)] with root cause

Main Code:

@Autowired private JavaMailSender javaMailSender; private void sendMail() { SimpleMailMessage msg = new SimpleMailMessage(); msg.setTo("to_1@gmail.com", "to_2@gmail.com", "to_3@yahoo.com"); msg.setSubject("Testing from Spring Boot"); msg.setText("Hello World \n Spring Boot Email"); javaMailSender.send(msg); } pom.xml
